Sheila is farming a plot of land that is a
trapezoid. The lengths of the two bases are
152.5 m and 230.4 m. The distance between
the bases is 104.3 m. Sheila has planted
corn on this field. She usually gets about 3.2
bushels per square meter of corn planted.
How many bushels can Sheila expect to
harvest from this field?
Please I need help !!
