Question

the area of a trapezoid is 36 square inches. The height is 4 inches and one bases twice the length of the other base. What are the lengths of the bases?

Answer 1

The formula for this is
`A= (1)/(2) ( b_(1) + b_(2) )h`. Filling in accordingly,
`36= (1)/(2)(x+2x)(4)`. This simplifies to
`36= (1)/(2)(3x)(4)` and 36=6x. Therefore, x = 6 so the bases are 6 and 12.
