Question

A triangle has a perimeter of 50 feet. If the three sides of the triangle are n, 4n - 4 , and 2n + 12 what is the length of each side?

Answer 1

The three sides are measured at 6 feet, 20 feet, and 24 feet, respectively.

Explanation:

50 = n + 4n - 4 + 2n + 12

50 = 7n + 8

42 = 7n

n = 6

6 feet

4(6) - 4 = 20 feet

2(6) + 12 = 24 feet

6 + 20 + 24 = 50
