Question

ΔABC ∼ ΔDEF,The ratio of corresponding sides of triangles are 9:25, then the ratio of

their areas
​

Answer 1

Area of triangle ABC/Area of triangle DEF

= Side^2/side^2

9^2 /25^2 = 81/625

Answer 2

Answer:

(ar∆ABC)/(ar∆DEF)=81/625

Step-by-step explanation:

(ar∆ABC)/(ar∆DEF) = (AB/DE)^2

( ar∆ABC)/(ar∆DEF)=(9/25)^2

(ar∆ABC)/(ar∆DEF)=81/625 is the answer..
