Question

A trapezoid’s longer base is three times the length of its shorter base. If the trapezoid has an area of 32 square feet and a height of 4 feet, what is the length of each base?

What is the answer?????

Answer 1

Below

Explanation:

b2 = 3 * b1 <===given

Area of a trapezoid = (b1 + b2)/2 * height b1 and b2 are the bases

32 = (b1 + 3 b1) / 2 * 4

32 = 4b1 /2 * 4

32 = 8 b1

4 = b1 then b2 = three times this = 12 ft
