Question

The area of a trapizoid is 69.6in and the altude is 8.7 in. Find the perniniter of the trapizoid

Answer 1

Explanation:

area of trapezoid

`= (sum~of~parallel~sides)/(2) * altitude\\69.6=(sum~of~parallel~sides)/(2) * 8.7\\139.2=sum~of~parallel~sides * 8.7\\sum~of~parallel~sides=(139.2)/(8.7) =16`

minimum parameter=16+2(8.7)=16+17.4=33.4 in
