Problema Solution
Find the lengths of the bases of the trapezoid described.
The height is 3 feet. One base is twice as long as the other. The area is 13.5 sq. ft.
Answer provided by our tutors
let lenght of base is l and 2l
area of the trapazoid is 1/2 x(sum of bases)x height
so given in the ques
13.5 = 1/2x(l+2l)x 3
13.5x2 =9l
l= 27/9
l=3
so the lenght of the bases is 3 ft and 6 ft
