Answer:

b2 = 10

Explanation:

You want to find the second base using the formula for the area of a trapezoid and other values given.

Setup

Fill in the given values to get a 2-step linear equation in b2.

A = 1/2h(b1 +b2)

136 = 1/2·16(7 +b2)

136 = 8(7 +b2) . . . . . . . . a 2-step linear equation in b2

Solution

Step 1 is to divide by the multiplier outside parentheses.

136/8 = 7 +b2

17 = 7 +b2

Step 2 is to subtract the constant.

17 -7 = 7 +b2 -7

10 = b2

The value of b2 is 10.
