Question

The sides of a triangle are in the ratio 2:3:5 and its perimeter is 40 cm. What is the measure of its shortest sides​

Answer 1

Answer:

Let the sides of triangles are 3x,4x and 5x.

And perimeter of the triangle is 144cm.

So , 3x+4x+5x=144

12x=144

x=12

so, the sides are triangle are 3(12)=36cm, 4(12)=48cm , 5(12)=60cm

Therefore, measure of it's shortest side = 36 cm

Answer 2

Answer:

The sides are 8,12 and 20

Explanation:

let the sides be 2x 3x and 5x

prerimeter = 40 cm

2x+3x+5x = 40

10x = 40

x = 40/10

x= 4

2x = 8

3x = 12

5x = 20
