What is a triangle with an area of 12 square units?
It's half the size of a quadrilateral with 24 square units ------------ One type of triangle with an area of 12 square units is the isosceles triangle with two 5-unit sides and one 6-unit side.
If the area of a rectangle is 18 square inches and the length of the rectangle is twice it's width what is the length and width of the rectangle?
A rectangle with one side that is double the length of the other side can be seen as two squares beside each other, that are half the area of the original rectangle, in this case 18 square inches / 2 = 9 square inches. The side of a square is the square root of the area, in this case the square root of 9 square inches, which is 3 inches. Now think about the rectangle again. What we just counted was the side of a square that made up one half of the rectangle you wanted to calculate the area of. So the shorter side of the rectangle is the same as our square, and the longer side is double the length. So the width of the rectangle is 3 inches, and the length is 2 * 3 inches = 6 inches. Or: Area = length x width (A=lw) Area = 18 (in2) Width = w Length = twice width (2w) 18 = (2w)w 18 = 2w2 9 = w2 3 = w The width is 3 in., the length (2w) is 6 in.
If figure ABCD is a square with sides that measure four and efg and h are the midpoints of the sides of abcd what is the area of square efgh?
If each side of ABCD is four then the midpoints divide each side in half, or two. If you draw the square efgh, each side is 2 times square root 2 from Pythagorean theorem. sqrt (2 sq + 2 sq) =2 square root 2. the area is the sides squared or 2 root 2 times 2 root 2 = 4 x 2 = 8
What is the perimeter of a square that has an are of 7 squared?
You can solve this in two steps. 1) Calculate the length of a side of the square, based on the area. 2) Once you have the length of the side, you can calculate the perimeter.
How do you prove the formula for the area of a triangle?
Easiest wayDraw a three inch by three inch square. add lines at one inch marks to form a small grid. draw line diagonally across to form two triangles. count the number of squares in one triangle (remember the squares with the diagonal line are only half a square)Did you get 4 1/2?A X B divided by two 3 X 3= 9 / 2 = 4.5To arrive to the forumla for area of triangle, lets look at the area of square and rectanlge first: Area of square: side x side Area of rectangle: length x width Notice that the formulas for area of square and rectangle is very similar. The squre is a special case only, so there is not much difference. Let's take the special case first- area of square: Area= side x side If I want to find the area of a triangle from this square, you have to divide the square in half diagonally. This means: (side x side)/2 = area of triangle Let's take a look at retangle now: Area of rectangle: length x width Similarly like the square, you divide the rectangle diagonally by half. This means: (length x width)/2 Conclusion: Thus, area of triangle= (base x height)/2 The base can be considered as one of the sides of the rectangle/square, and the height can be considered as the other side of the rectangle/square. THE FORMULA OF TRIANGLE COMES FROM HALF THE AREA OF RECTANGLE/SQUARE! Visit quickanswerz.com for more math help and tutoring!Area is measured in square units. If we are given a region we divide the region into unit squares.Then we count the number squares, which is the area of the region.Consider a rectangle of length 10 units and width 5 units.The area of the rectangle is 50 square units.It is because we can divide the rectangle into 10 equal parts along the length.Similarly, we can divide the rectangle into 5 equal parts along the width. Now we have divided the entire rectangle into unit squares.If we count the number of squares we get 50 unit squares.We get this by multiplying the length and the width. Area = Length*Width square units.This is the same for a parallelogram too.Area of a parallelogram is base * height square unitsThis is how the concept of area has come.We can find the area of the triangle also.A rectangle or a parallelogram can be divided into two equal triangles by a diagonal.Half of the area of the rectangle(or parallelogram) gives the area of the triangle.In fact, we can extend any triangle into an parallelogram.So, we get the formula, area of a triangle = (base* height)/2 square units.Source: www.icoachmath.com
What happens to the area of the square if its side is halved?
Then its area will only be a quater of once it was.
What is the relationship between right triangles and the areas of squares?
A right angle triangle with two side lengths that match that of an equivalent square will have exactly half the area of the square.
How do you find the area if perimeter is given?
If the area is a square, 1/4 of the perimeter is the length of one side. That length squared is the area. The area will be the product of two numbers whose sum is half the perimeter.
What is a triangle with an area of 12 square units?
It's half the size of a quadrilateral with 24 square units ------------ One type of triangle with an area of 12 square units is the isosceles triangle with two 5-unit sides and one 6-unit side.
What is the area of a square if one side is two and a half feet?
definition of a square: all sides are congruent (equal) Therefore, all sides are 2.5 feet. To find area, you multiply length by width....so multiply 2.5x2.5
What is the dimensions of two square acres?
A square area that was two acres would be about 295 feet on each side.
When you fold a square paper vertically the new rectangle has a perimeter of 39 inches what is the original area of the square?
169 square inches. Folding the square in half leaves 2 edges of the original side length and two of half the side length. Therefore: perimeter = side + 1/2 side + side + 1/2 side = 3 sides ⇒ 3 sides = 39 inches ⇒ 1 side = 39 inches ÷ 3 = 13 inches ⇒ area_original_square = 13 inches x 13 inches = 169 square inches.
A right angle triangle one side is 5.30 m and the other side is 5.30M and the other side is 7.30 M What is the area of this rightangle triangle?
Remember that a right triangle is just a square split in two along the diagonal. So you need to find half of the area of a 5.3 x 5.3 square. (5.3*5.3)/2
How do you work out the difference of the area of a circle and the area of a square when the radius of the circle is 6cm and the side of length of the square is 12cm?
Do you know how to find the area of a circle when you know the radius ? Good! Do that. Do you know how to find the area of a square when you know the length of the side ? Good! Do that. Now you have two numbers ... the area of the circle and the area of the square. The problem wants you to find the difference of these two numbers. Do you know how to use subtraction to find the difference of two numbers ? Good! Do that.
What is the area of a square if two sides are 728 miles?
In a square, if one side is 728 miles, then they all are.The area is (728)2 = 529,984 square miles.
Why do you have to cut the area of a triangle in half?
Because otherwise you would have found the area of the rectangle/square (the rectangle/square being if you put two of the triangles together).
What is the side length in meters of a square that has an area of 50 square meters?
7.071 centimetres (to two decimal places).
