Question

A triangle has a perimeter of 112 cm. Each of the two longer sides of the triangle is three times as long as the shortest side. Find the length of each side of the triangle.

Answer 1

Two sides have a measure of 48 cm and the shortest side is 16 cm.

Explanation:

this is an isosceles triangle

let x = length of shortest side

let 3x = length of other two sides

find x:

3x + 3x + x = 112

7x = 112

x = 16

3x = 48
