Question

The perimeters of two similar triangles triangle ABC and triangle PQR are 35cm and 45cm respectively, find the ratio of the area of first triangle to the area of second triangle.

Answer 1

Solution:

perimeter of∆ABC/perimeter of∆PQR = 1st side of ∆ABC/2nd side of ∆PQR

35/45=7/9

Now , we know that The ratio of two similar triangles are equal to the square of ratio of there corresponding sides

(7/9) square = 49:81 ans

Answer 2

Step-by-step explanation:

perimeter of triangle ABC/perimeter of triangle PQR=AB/PQ

AB/PQ=35/45

=7/9

area of triangle ABC/area of triangle =(AB/PQ)^2

=(7/9)^2

49/81
