In order to find the area of the triangle, we can use the Area formula of the triangle.

Given base of the triangle, b = 8m

Given height of the triangle, h = 4m

Hence > Area of the triangle, A = ½ * 8m * 4m

In order to find the area of the circle, we can use the Area formula of the circle.

Given radius of the circle, r = 10cm

Hence Area of the circle, A = π * (10cm)

Area of the circle, A = (3.14) * 100cm
