The area of a trapezoid is 69.6 in2 and its altitude is 8.7 in. Find the perimeter of the trapezoid if the sum of its legs is eq
Murljashka [212]
To answer this, you will find the sum of the bases by using the area of a trapezoid formula:

A = 1/2 x h x (b1 + b2) - You will represent the area of the 2 bases as x,                                                  because it says the sum of the bases so this can be 
                                     written as 1 term, x
69.6 = 1/2 x 8.7 x (x);  solve for x
69.6 = 4.35x; divide both sides by 4.35
x = 16 in.

If 16 inches is the sum of the 2 bases and the sum of the legs, than you will double this answer to find the perimeter.

16 in x 2 = 32 inches

The perimeter is 32 inches.
