area of a trapezoid is h/2(b1 + b2)

OpenStudy (anonymous):

set one base as 4x, then the other must be 5x

OpenStudy (anonymous):

plug the values in: 2/2 (5x + 4x) = 36

OpenStudy (anonymous):

the 2/2 just equalts 1, ull then get 9x = 36, x = 4, plug in back to 4x and 5x, u get 16m and 20m for the 2 bases
