Question

the perimeter of a triangle is 100cm and the ratio of their sides is 1:2:3 then what is the area in cmsquare in

Answer 1

Perimeter =100cm

Rule to find perimeter of triangle =a+b+c

Let sides are 1x,2x,3x

So,

100cm=1x+2x+3x

100cm =6x

X=100 divided by 6

X =16.6

First side=1x=1×16.6=16.6

Second side=2x=16.6 ×2=33.2

Third side =16.6 ×3=49.8
