do you know how to find the area of a SQUARE given the length of the side?

To find the area of a square you will multiply the length by the width soo....|dw:1444958571785:dw|

Well to find the area of a trapezoid you will use the formula...\[A = \frac{ (a + b) }{ 2 } h\]

OpenStudy (rainbow_rocks03):

ok

563blackghost (563blackghost):

Now we first must determine the top part of trapezoid as you can see is shows 38 meters but its not the complete are of the trapezoid what is the complete meter?
