Q. 41

If such that AB = 9.1 cm and DE = 6.5 cm. If the perimeter of is 25 cm, then the perimeter of is
A. 36 cm

B. 30 cm

C. 34 cm

D. 35 cm

Answer :

Given ΔABC ~ ΔDEF such that AB = 9.1 cm and DE = 6.5 cm.


Given that ΔABC and ΔDEF are similar triangles such that AB = 3 cm, BC = 2 cm, CA = 2.5 cm and EF = 4 cm.


We know that ratio of corresponding sides of similar triangles is equal to the ratio of the perimeters.



Consider,




P(ΔABC) = 35 cm
