Question

The perimeter of a triangle is 42 yards. The first side is 5 yards shorter than the

second side, and the third side is 2 yards shorter than the first side. What is the length
of each side?

Answer 1

Answer: Is your question "What is the length of each side?"

Let x = the length of the second side

Let x - 5 = the length of the first side

Let (x - 5) - 2 = the length of the third side

P = a + b + c

x + x - 5 + x - 7 = 42

3x - 12 = 42

3x = 54

x = 18 yards

x - 5 = 13 yards

x - 7 = 11 yards
