Question

The perimeter of a triangle is 122 centimeters. If two sides are equally long and the third side is 8 centimeters longer than the others, find the lengths of the three sides.

Answer 1

2 sides are 38cm long

The third is 46cm long

Explanation:

We can use the following equation to solve

`122 =x + x + (x + 8)`

Reduce

`122 = 3x + 8`

114÷3 = x

x = 38

We then add 38 and 8 because the 3rd side is 8cm longer
