Question

ABCD is a rectangle whose lenght and breath 26 m by 15 m. ADE is a triangle such that EF⊥ AD and EF= 8 cm. Calculate the area of the shaded region? with explanition

Answer 1

Answer:

Given length of rectangle = 32m and breadth = 18m We know that area of rectangle = length x breadth Therefore area of the rectangle = AB x BC = 32 m x 18 m = 576 m2 Also given that base of triangle = 18m and height = 14m and EF⊥ AD We know that area of triangle = ½ x base x height Area of the triangle = ½ (AD x FE) = ½ (BC x FE) [Since AD = BC] = ½ (18 m x 14 m) = 126 m2 Area of the shaded region = Area of the rectangle – Area of the triangle = (576 – 126) m2 = 450 m2Read more on Sarthaks.com - https://www.sarthaks.com/690510/in-fig-abcd-is-rectangle-with-dimensions-32-by-18-ade-is-triangle-such-that-efad-and-ef-14-cm
