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 1

Answer:

49/81

Step-by-step explanation:

perimeterof two similar ∆ is = to the ratio of its sides .

So,

(35)/(45)

ratio of sides=7/9

ratio of area is equal to square of sides

(7)2/(9)2

49/81
