Question

Perimeter of two similar triangles are 30 cm and 20cm if one side of first triangle is 12cm and then find the length of corresponding side of other triangle

Answer 1

Heya Frnd. ............ ☺

Perimeter of the 2 triangles = 30 cm & 20 cm respectively.

Let 's name the triangles as ABC & PQR

So,

AB/PQ = PERIMETER ABC/ PERIMETER PQR

=> 12/PQ = 30/20

=> PQ = 2 × 12 / 3

$= > \: \boxed{ PQ \: = \: 8}$
