Question

What is the length of the shortest side if the perimeter is equal to 60 feet?

5 ft

18 ft

29 ft

13 ft

Answer 1

13ft

Explanation:

2x + 8 + 3x – 2 + 5x + 4 = 60

10x + 10 = 60

10x = 50

x = 5

Shortest side: 3x – 2 = 3(5) – 2 = 13

Answer 2

13 ft

Explanation:

Perimeter of a triangle = 2x + 8 + 3x - 2 + 5x + 4

and the perimeter is equal to 60 feet

so

2x + 8 + 3x - 2 + 5x + 4 = 60

10x + 10 = 60

10x = 50

x = 5

Sides:

2x + 8 = 2(5) + 8 = 18

3x - 2 = 3(5) - 2 = 13

5x + 4 = 5(5) + 4 = 29

Shortest side = 13 t
