Question

Find the area of shaded portion if ABCD is rectangle and BE=8cm, FD=4cm, BC=10cm, DC=25cm

Answer 1

Answer:

159 cm^2

Step-by-step explanation:

To find the area of shaded portion we should subtract the area of triangle BCE and triangle AEF from the rect angle's area.

now area of rectangle = length ×breadth =25×10=250 cm^2

area of triangle BCE=8×10/2=40cm^2

area of triangle AEF

=(AB-BE)×(AD-FD)/2 (AB=DC)rectangle property

(AD=BC) rectangle property =25-8×10-4/2

=51cm^2

so area of shaded region

=250-40-51=159 cm^2
