Question

A trapezoid has an area given by A = (b 1 + b 2)h, where b 1 is the length of one base, b 2 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 1 in terms of the other variables.

Answer 1

A = (b1 + b2)h first distribute the h
A = b1 h + b2 h then subtract b2 h from both sides
A - b2 h = b1 h then divide both sides by h
b1 = A/h - b2 plug in 14 for A
b1 = ....

Answer 2

thank you

Answer 3

what does b1 =

Answer 4

b1 = A/h - b2
then to get the answer that the question wants you to get,
plug in 14 for A

Answer 5

Ok. Thanks
