Question

A trapezoid has sides of length 11 inches, 1.5 inches, 11 inches, and 19.1 inches. What is the perimeter?

Answer 1

The Perimeter of the trapezoid = 42.6 inches

Explanation:

______

Formula:

let a , b , c , d be consecutively the lengths of the sides of the trapezoid

then

The Perimeter of the trapezoid = a + b + c + d

___________________________________

Suppose a = 11 , b = 1.5 , c = 11 , d = 19.1

therefore,

The Perimeter of the trapezoid = a + b + c + d

= 11 + 1.5 + 11 + 19.1

= 42.6
