The Perimeter of a triangle is 71 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.

Solution

If two sides are equally long and the third side is 8 centimeters longer than the others,

Let equal sides be x cm

third side be x+8 cm

Permieter = x+x+x+8 = 71

3x+8 =71

3x= 63

x =21 cm

The lenght of three sides: 21cm , 21cm , 29 cm would be the lenght of three sides of triangle
