Question

The perimeter of a triangle is 2.96m.if the length of its sides are in the ratio 1:2:5,find the length of each side in cm​

Answer 1

Let the ratio be 1x, 2x, 3x

By adding ratio we get 1x+2x+5x

=8x=2.96m

x=2.96/8

=0.37

now therefore

1x=0.37

2x= 2*0.37

=0.74m

5x=5*0.37

=1.85m

now

FIRST SIDE WILL BE =0.37M

SECOND SIDE WILL BE =0.74M

THIRD SIDE WILL BE =1.85M

BY ADDING ALL THREE SIDE WE GET

=2.96M
