Question

the sides of triangle are in ratio 2:3:5 and its perimeter is 180cm. Find its area​

Answer 1

Answer:

let the sides of triangle be 2x,3x and 5x.

So perimeter of triangle = sum of its all sides

180= 2x+3x+5x

180= 10x

180/10= 10x/10

18= x

so 2x = 2 x 18 = 36

3x = 3x18=54

5x = 5x18= 90

Answer 2

Answer:

let the sides of triangle be 2x,3x and 5x.

So perimeter of triangle = sum of its all sides

180= 2x+3x+5x

180= 10x

180/10= 10x/10

18= x

so 2x = 2 x 18 = 36

3x = 3x18=54

5x = 5x18= 90
