Question

The perimeter of a triangle is 37. One side of triangle is one foot longer than the second side. The third side is tgree feet longer than the second side. Find the lenghts of all three sides

Answer 1

First: 12 feet

Second: 11 feet

Third: 14 feet

Explanation:

Let the second side of the traingle be x

First side of the triangle= x+1

Third side of the triangle= x+3

x+x+1+x+3 = 37

3x+4 = 37

3x = 37-4

3x = 33

x = 11

First side of the triangle= (11)+1

= 12

Second side of the triangle= 11

Third side of the triangle= (11)+3

= 14
