Show how to work out square meters?
Square meters of what? If you want the area in square meters of a rectangle, just multiply the length times the width (both in meters). To get square meters of other figures, other formulae are required.
Are the diagonals of a rectangle congruent always?
Yes. You can show this by SAS of two right triangles. Consider rectangle ABCD. AD and BC are the same length and AC and BD are the same length because opposite sides are congruent. The angles ADC and BCD are congruent since it is a rectangle and the angles are right angles. So the triangles ADC and BCD are congruent and their hypotenuses (the diagonals of the rectangles) are congruent.

Diameter height length is given how to find volume of cylinder laid horizontally?
Whether a cylinder is laid horizontally, or standing vertically, it has the same volume.The volume of a cylinder is the 'square area' of the circle at the end, multiplied by its length/height.The area of a circle is Pi x diameter. (The inner diameter is probably best. The final calculation will then show the total internal volume in cubic units.)End area x length = volume.If the cylinder is laid horizontally, the distance between the ends would be called its length. If the cylinder is standing up, the distance between the ends is called its height.
Find a counterexample to show that the conjecture is false?
if the qoutient of two numbers is positive, then both numbers must be a rectangle.
What is the width of the rectangle if the area is 132 feet and the length is 12 feet?
The equation for a rectangle is h(height) x w(width) = area . By manipulating the equation we can show that width=area/length. So 132/12=11. This means the width of the rectangle is 11.
Show a rectangle that has permeter and area?
The area is the length times the width. The perimeter is two times the length plus two times the width.
Show the height width length of a rectangle?
A rectangle is a two dimensional object: height, width and length are three dimensions.
The width of a rectangle is one half of its length The area is 128 ft what is the width Please show the math applied?
I guessed and the answer is 8
The width of a rectangle is 11 cm mire than the length the area of the rectangle is 1302 cm label which is the length and which is the width show work too please?
W = width of rectangle L = length of rectangle A = area of rectangle W x L = A (L+11) x L = A L squared + 11 L - 1302 = 0 solve for L by quadratic equation or by factoring: (L-31)(L +42) = 0 L = 31 W = L+11 = 42
Which number sentence does show the area of a rectangle with the length of 4 centimeters and a width of 9 centimeters?
4 cm * 9 cm = 36 square cm.
Can you find the area of a rectangle if the problem doesn't show you the base and height?
The one alternative to find the area of a rectangle is when you are given the length of one diagonal and its slope.
What are Square and cubic measurements?
Square meters show that there is a flat area. We calculate the area by length times width. This is two-dimensional. Cubic meters show that there is a volume. We calculate the volume by length times width times height. That is three-dimensional.

How do you find the total area?
Well if you just have a rectangle or a square, that's easy. Just times the length by the width. For example: Length = 5cm Width = 6cm Area = 20cm squared When you write the area, put a little '2' by the measurement to show 'squared'. However, if you have an irregular shape, split it into small rectangles then use the steps above on each rectangle to find the area. Then add them all together - remembering the little 2 to show that it's squared. For triangles, just use the ordinary rectangle steps, then half the answer. This is because if you put a triangle on that was the same size, it would be a rectangle (sorry, I'm not too good at explaining). If you have other shapes - ask someone else. I'm not really sure for that. Now, next lesson, how to do long multiplication! Just kidding, don't worry! Sorry it's so long and boring!
Which rectangle does NOT show 12 same-size squares?
To have 12 same size squares in a rectangle the grid of squares will be 1x12, 2x6 or 3x4. This means that the ratio of the length to the width is either 1:12, 2:6, 3:4, 4:3, 6:2 or 12:1. If the ratio of the length to width is none of those, then 12 same-size squares cannot fit.
How do you calculate the surface area of a cylinder?
OK. Let me give you an example.Lets suppose the radius of a cylinder is 3.5 ft, the Diameter is 7 ft and the height is 14 ft. find the surface area. Show all your work.In order to find the surface area you have to calculate all the areas. and then add them up.Area of a circle is Pi times the radius squared.Pi is 3.14Area of a circle is 3.14 X 3.5 ft2Area of a circle is 3.14 X 12.25 ftArea of a circle is 38.465 ft2Now a cylinder has two circles that equal each other, so all we have to do is multiply 38.465 ft2 X 2.Area of both circles is 76.93 ft2Second you have to find the area of the rectangle that is wrapped around the cylinder. When the rectangle is wrapped around the cylinder it creates a circumference which is the length of the rectangle.So we need to find the circumference.Circumference is Pi times the diameter.Pi is 3.14Circumference is 3.14 X DCircumference is 3.14 X 7 ftCircumference is 21.98Now that we know the Circumference we can find the area of the rectangle wrapped around the cylinder.Area of a rectangle is Length times the Width.(The height of a cylinder is also the width of the rectangle).Area of a rectangle is 21.97 X 14 ftArea of a rectangle is 307.72 ftOK. we calculated all the areas. BUT we still aren't done. We have to add all the areas up.76.93 ft2 + 307.72Surface Area is 384.65
