Question

the area of triangle is equal to that of a square of side 60m find the side. of triangle whose. corresponding altitude is 90 m

Answer 1

It is given that area of triangle is equal to area of a square of side 60m.
the altitude of triangle = 90m

area of square = 60*60 = 3600 m^2
so area of triangle = 3600m^2
⇒ 1/2 bh = 3600
⇒ 1/2 × b × 90 = 3600
⇒ b = 3600×2/90
⇒ b = 80m

So the side of the triangle is 80m.
