Question

The side of the smaller triangle, out of the two similar triangles are $4cm,5cm$ and $6cm$ respectively. If the perimeter of the larger triangle is $90cm$, then what are the lengths of the sides of the larger triangle?

Answer 1

Sides of larger triangle will be in the ratio of $4:5:6$ whose perimeter is $90$cms.

Sum of ratio $=4+5+6=15$

Length of first side. $=4\times \frac{90}{15}=24$ cms.

Length of second side $=5\times \frac{90}{15}=30$cms.

Length of third side $=6\times \frac{90}{15}=36$cms.
