Question

The perimeters of two similar triangles ∆ABC and ∆PQR are 35cm and 45cm respectively, then the ratio of the areas of the two triangles is____answer
__________​

Answer 1

as we know that ratio of areas of 2 similar triangles is equal to square of ratio of their corresponding sides of perimeter

that is,

area ABC=(35)^2

area PQR (45)^2

=(7)^2/(9)^2

=49/81

thank you
