Question

13 The perimeters of two similar triangles AABC and APQR are 15cm and 25cm
respectively, then the ratio of the areas of the two triangles is
​

Answer 1

Answer:

Perimeter of ABC/Perimeter of PQR = Scale Factor

15/25 = Scale Factor

3/5 = Scale Factor

Area of ABC/Area of PQR = Scale factor^2

Area of ABC/Area of PQR = 3/5^2

Area of ABC/Area of PQR = 9/25

SO THAT RATIO IS 9:25
