Question

5)

The perimeter of a triangle is 60 feet. If the sides are in the ratio 3:4:5, find the
length of each side.

Answer 1

15,20,25

Explanation:

The ratio of the sides is 3:4:5

So 3x + 4x + 5x = 60

12x = 60

x = 60/12

x = 5

The sides are therefore

3x = 3*5 = 15

4x = 4*5 = 20

5x = 5*4 = 25

Total 60 just what it should be
