If the height of the trapezoid is 16m, one base is 20m, and the are is 224msquared, find the length of the other base.
Rose's garden is in the shape of a trapezoid.?
Area of a Trapezoid:
A = [ h (b1 + b2) ] /2, where b1 and b2 are the two bases of the trapezoid.
Thus, you have:
224 = [ 16( 20 + x)) ] /2 = [ 320 + 16x] /2 = 160 + 8x. Subtract 160 from both sides of the equation.
84 = 8x, so x = 10.5 meters.
