Question

Find two possible lengths of the bases of a trapezoid with a height of 1 foot and an area of 9 square feet. Explain how you found your answer.

Answer 1

I agree the answer is 18

Answer 2

Write the formula: A=a+b/2(h). Sub in what you know: 9=a+b/2(1). Divide by the height: 1: 9=a+b/2. Multiply by 2: 18=a+b. Now a is typically smaller than b so my guess would be a=6 b=12 but you could pick any numbers as long as they equal 18 :)
