Question

A trapezoid has an area given by A =1-2(b1+b2)h,where b1,is the length of one base, b2 is the length of the other

base, and h is the height. If the trapezoid has an area of 14 square units, solve for b in terms of the other variables.

Answer 1

b1 = (28/h) -b2

Explanation:

Filling in the given value for A, you have ...

14 = (1/2)(b1 +b2)h

Multiply by 2/h:

28/h = b1 +b2

Subtract b2:

b1 = (28/h) -b2
