Question

A triangle has sides in the ratio 4:3:5. the perimeter of the triangle is 60cm. what length of the shortest side?

Answer 1

Length of the shortest side = 15cm

Explanation:

Sum of the ratio = 12

`First \ side = (4)/(12) * 60 = 20cm\\\\Second \ side = (3)/(12) * 60 = 15 cm\\\\Third \ side = (5)/(12) * 60 = 25cm`

Answer 2

15cm

Explanation:

4+3+5=12

60/12=5

4*5=20

3*5=15

5*5=25

20cm:15cm:25cm

Hope it helped!
