3. In the figure, a triangle is
removed from a square of
sides 9 m. Find the area of
the figure.
9 m​

Answer 1

Answer:

For square,Side=9m

Area of square= S^2 = 9^2 = 81 m^2.

For Traingle,Base= 1/2 of 9 = 4.5m

Height = 9m

Area of triangle = 1/2 b h = 20.25m^2.

Area of fig = Area of square - Area of triangle

= 81 - 20.25 = 60.75 m^2.
