Question

The sides of a triangle are in the ratio 4:5:2. Find the sides of the triangle, if it's perimeter is 660 cm

Answer 1

Let us assume the three sides of the triangle as 4p, 5p and 2p

Perimeter of the triangle = 660 cm

Perimeter of the triangle = ( 4p + 5p + 2p ) cm.

Hence,

(4p + 5p + 2p ) = 660

11p = 660

p = 660 ÷ 11

p = 60 cm

First Side => 4p = 4 × 60

= 240 cm

Second Side => 5p = 5 × 60

= 300 cm

Third Side => 2p = 2 × 60

= 120 cm

Answer 2

Answer:

Step-by-step explanation:

Let the sides to be 4x,5x,2x

Now 4x+5x+2x =660cm

11x=660cm x= 60 cm then the sides are 4×60 =240cm ,5×60=300cm ,2×60=120cm
