Question

Two sides of a triangle have the same length. The third side measures 5 m less than twice that length. The perimeter of the triangle is 11 m. Find the lengths of the three sides.

Answer 1

Answer: side 1 = 4m, side 2 = 4m, side 3 = 3m

2 times 4 = 8
8 - 5 = 3

Perimeter of triangle = 4 + 4 + 3
P = 11 m
