Question

2.5m
in the figure, a triangle is
removed from a square of
sides 9 m Find the area of
the figure​

Answer 1

Step-by-step explanation:

Given, square of side = a = 9 m

Height of the triangle = h = 9 m

Base of the triangle = b = 9 m

Area of the triangle =1/2*b*h  = 1/2*9*9  = 40.5 m²

Area of the square = a² = 9² = 81 m²

Area of the figure after triangle is removed from a square

= Area of the square - Area of the triangle

= 81 - 40.5 = 40.5 m²

Hence, the area of the figure is 40.5 m².
