Q6 of 42 Page 214

Δ ABC ∼ Δ DEF. BC = 3 cm EF = 4 cm and area of ΔABC = 54cm2. Determine the area of ΔDEF.

Given, BC = 3 cm EF = 4 cm


Also, area of Δ ABC = 54cm2


Need to find area of Δ DEF


⇒ since, Δ ABC ∼ Δ DEF


⇒


⇒


⇒


⇒ = ar(Δ DEF)


⇒ ar(Δ DEF) = 96 cm2


Hence, the area of Δ DEF is 96cm2
