Question

The length of the sides of a polygon are in the ratio of 3: 4: 2: 5. If the perimeter is 84 cm, find the N length of the shortest side​

Answer 1

12 cm

Explanation:

First, divide the perimeter by the sum of ratios.

=> 84 / (3 + 4 + 2 + 5)

=> 84 / 14

=> 6

Shortest side

= 2x

= 2(6)

= 12 cm
