Question

The area of a trapezoid is A = 0.5(base 1 + base 2)h. Find base 1 if A = 100, h = 5, and base 2 = 12
A. 20
B. 30
C. 25
D. 2

Answer 1

you are given the formula A = 0.5(base 1 + base 2)h
you are also given A = 100, h = 5, and base 2 = 12
so you can plug these into the formula to get

100 = 0.5(base 1 + 12)*5

solve for base 1

please let me know what you get

Answer 3

are you still there?

Answer 4

would it be 20?

Answer 5

nope, let's start from the beginning

100 = 0.5(base 1 + 12)*5

divide both sides by 0.5, what do you get?
