The height of a trapezoid is 8 inches, one of the bases measures 24 inches. If the area of the trapezoid is 160 square inches, find the length of the other base.

Question

anonymous · Answer

The equation is 24 + x times 8 / 2 = 160 ? right?

raden · Answer

The area of trapezoid = 160
1/2 * (24+x) * 8 = 160

raden · Answer

yes, solve for x

I always get confused when I start solving with these kinds of equations..

raden · Answer

1/2 * (24+x) * 8 = 160
look that 1/2 * 8 = 4, u have
4 (24+x) = 160
divided by 4 to both side, giving us
4/4  *  (24+x) = 160/4
24 + x = 40

it looks easier now :)
