If "a" and "p" equal hours.
a + p = 30 would be the correct choice.
Answer:
in first question, answer is 12
in second question, answer is -12
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.
