Question

The sides of a triangle are in the ratio 3 ratio 5 ratio 7 ratio and its perimeter is 60 cm find its all sides

Answer 1

Answer:

Side of triangle = 3:5:7

Let the side be x

3x,5x,7x are the side of triangle.

Perimeter = 60cm

First you have to remember the formula of perimeter of triangle

The formula is '' sum of all sides''

Now we solve this

3x + 5x + 7x = 60

15x = 60

X = 60/15

X = 4

So the sides are 3x = 3 ✖ 4 = 12cm

5x = 5 ✖ 4 = 20cm

7x = 7 ✖ 4 = 28 cm
