The length of rectangle is 2 inches more than its width The area of the rectangle is 15 square incheswhats the width and length?
They are: 3 inches and 5 inches respectively
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
How do you determine length and width if given the area?
What geometric shape?Since you failed to mention the shape of the area, we will have to assume it's a rectangle of some sort. (Note that a square is a special case of rectangle.) There are an infinite number of rectangles that will contain a given area.length x width = areaOne equation like this cannot be used to find twounknown quantities. You would have to be given more information: perhaps the perimeter or either the width or the length, or perhaps you have been told the ratio of length to width.Alternatively, if you know that your rectangle is in fact a square, then its length and width equal the square root of the area.
The length of a rectangle is five feet more than twice its width and the area of the rectangle is sixty-three Find the dimensions of the rectangle?
Let the width = X. The length is twice the width plus 5. So the length must be 2X + 5. Area = 63 ft squared = X multiplied by 2X + 5 = 2X squared + 25. 2X squared = 63 - 25 = 38 2X = square root of 38. Therefore the width is the square root of 38 divided by 2 and the length is the square root of 38 plus 5.
The length of a rectangle is 2 inches more than its width the area of the rectangle is 15 square inches what are the length and width of the rectangle?
Call the width of the rectangle x. Call the length of the rectangle x + 2. The area of the rectangle would be the length times the width. We know this is 15 square inches. Set up the equation and solve for x. (x +2)x = 15 x2 + 2x = 15 x2 + 2x - 15 = 0 Factor the quadratic equation: (x - 3)(x + 5) = 0 x = 3 or x = -5 Since length can't be negative, discard the answer -5. If x = 3, then the width is 3 and the length is x + 2 or 5. 5 x 3 = 15 which equals the area.
Does a cylinder or rectangle have more surface area?
rectangle
Surface area of square?
It is the area of the square. Nothing more, nothing less.
What is the dimension of a 15 square meter surface?
There are many possible dimensions which would have a surface area of 15 square metres, from a circle of radius 2.185 metres, a triangle of base 10 and height 3, a square of 3.8729, a rectangle of 5 by 3, and many, many more.
Is it sometimes always or never true that the perimeter of a rectangle is numerically greater than its area?
Sometimes. Experiment with a small square and with a large square (though any shape rectangle will do). A square of 4 x 4 has a perimeter of 16, and an area of 16. A smaller square has more perimeter than area. A larger square has more area than perimeter.
The length of a rectangle is 1 inch more than 2 times its width the area of the rectangle is 36 square inches what is the length of the rectangle?
9 inches
The length of a rectangle is 4 more than 3 times the width. if the perimeter of the rectangle is 18.4 cm what is the area of the rectangle?
Length of rectangle: 7.9 cm Width of rectangle: 1.3 cm Area of rectangle: 7.9 times 1.3 = 10.27 square cm
The length of a rectangle is 2 inches more than its width the area of the rectangle is 65 square inches what are the length and width of the rectangle?
Its length is 1+ square root of 66 ft and its width is -1+ square root of 66 ft
what- the area of a rectangle is 36 square centimeters. The length is 1 foot more than twice the width.What is the width of the rectangle?
4 cm
The area of a rectangle is 36 square inches the length is 1 inch more than twice the width what are the dimensions of the rectangle?
9" x 4"
How is a square more specific than a rectangle?
A square has all four equilateral sides, whereas a rectangle has two sets opposite sides that are congruent. A rectangle can be a square, but a square can not be a rectangle.
Why is a square a rectangle?
A rectangle is a parallelogram with angles of 90 degrees. A square has those properties (and more) so it is a rectangle.
Why is a square a rectangle but a rectangle is not a square?
a rectangle doesn't have four equal sided measurements, which is the definition of a square. also it can take one or more squares to make a rectangle but u can't make a rectangle into a square.
