If ∆ABC ~ ∆DEF, and BC = 4 cm, EF = 5 cm and the area of triangle ABC = 80 cm2, then the area of the triangle DEF is:
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 125 cm2.
We have given in the question,
In ∆ABC ~ ∆DEF
BC = 4 cm, EF = 5 cm and the area of triangle ABC = 80 cm2
(BC/EF)2 = Area of ABC/Area of DEF
16/25 = 80/x
x = 125 cm2
