Question

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

Answer 1

Let he side of larger triangle be - $4x,5x,6x$

$4x+5x+6x=90$

$15x=90$

$x=6$

$\therefore 4x=4\times 6=24$

$5x=5\times 6=30$

$6x=6\times 6=36$

$\therefore$ Sides of larger triangle $=24cm,30cm$ and $36cm$.
