Question

the two shorter sides of a triangle are the same length. the length of the longer side is 5 m longer than each of the shorter sides. the perimeter of the triangle is 29 m. what is the length of the longest side of the triangle? a. 8 m b. 12 m c. 13 m d. 17 m

Answer 1

The length of the longer side of the triangle is c. 13 m

Answer 2

Let the length of the shorter sides be x, then
Perimeter = x + x + x + 5
29 = 3x + 5
3x = 29 - 5 = 24
x = 24/3 = 8

Therefore, the length of longest side is 8 + 5 = 13 m.
