Answer» For similar triangles Area1/Area2 = (length 1/length)^2 Given (length1/length2) = 4/9 Hence, Area1/Area2 = (4/9)^2 Area1/Area2 = 16/81 Therefore, ratio of area of triangle = 16:81 (b) is correct option

5. If ratio of corresonding sides of two similar triangles is 4:9, then the ratio of their areas isa) 81:16c) 2:3b 16:81d) 94

Answer»

For similar triangles

Area1/Area2 = (length 1/length)^2

Given (length1/length2) = 4/9

Hence, Area1/Area2 = (4/9)^2

Area1/Area2 = 16/81

Therefore, ratio of area of triangle = 16:81

(b) is correct option
