If the base is a rectangle, use the formula for the area of a rectangle.
A traingle covers half the area of a rectangle with the same base and [perpendicular] height.
Divide the rectangle in two triangles and then use the pythagorean theorem to find the remaining sides.
you need length and width length multiply width = area length + length + width + width = perimeter

if a rectangle has width of 5 and diagonal with lenght of 13, what is the area of the rectangle? Use Pythagoras' theorem to find the length of the rectangle which will be 12 5*12 = 60 square units

Use the Pythagorean Theorem (a2 + b2 = c2, where a and b are the legs and c is the hypotenuse) and then you will know the base of the rectangle (which would be a or b, depending on which you use). Then you can multiply the base and height to find the area of the rectangle!Great answer!
The volume of the rectangle is of no use to you, since the volume of every rectangleis zero. What you need to know is the rectangle's area and length.You're supposed to know that the area is the product of (length) times (height).So if you know the area and one of the dimensions, you can use that formula tofind the other dimension.
If the length and the breadth of the rectangle represent the two numbers, then the area of the rectangle is equal to their product. But, how do find the area? You multiply the two numbers. So this appears to be a long way to do something that is inherently straightforward!
I assume redtangle is supposed to be rectangle? So the formula to find the area is length x width. For example: rectangle is 8" x 4" so 8 x 4 = 32 square inches (32in2).
It depends on the size of the triangular prism, but depending on the side of the prism you use the triangle area formula to find it or the rectangle area formula to find it.
