Question

If the sides of a thiangle in the ratio 3: 5 :7 are and it's peremeter is 300, find the shortest side of
the triangle.​

Answer 1

Let the sides be

2x, 5x and 7x.

Given,

shortest side = 6 cm.

But shortest side = 2x

Thus, 2x = 6

so, x is 3

Perimeter of ∆ = 2x + 5x + 7x

= 14x

= 14*3

= 42 cm..

Answer 2

Let the sides be

2x, 5x and 7x.

Given,

shortest side = 6 cm.

But shortest side = 2x

Thus, 2x = 6

so, x is 3

Perimeter of ∆ = 2x + 5x + 7x

= 14x

= 14*3

= 42 cm..

Answer 3

Let the sides be

2x, 5x and 7x.

Given,

shortest side = 6 cm.

But shortest side = 2x

Thus, 2x = 6

so, x is 3

Perimeter of ∆ = 2x + 5x + 7x

= 14x

= 14*3

= 42 cm..
