Question

a)Find the area of rectangle ABCD.
b)Find the area of triangle BCE.
c)Find the area of triangle BEF
d)What is the area of the shaded portion?​

Answer 1

Answer:

Area of rectangle - length * breadth

14cm * 8cm

112cm²

Answer 2

so answer is

a) area of rectangle ABCD = L×B

= 8×14 = 112cm^2

b) area of triangle BCE = 1/2 × base × height

= 1/2 ×5 × 8 = 20 cm^2

c) area of triangle BEF = 1/2 × base × height

= 1/2 ×14 × 8 = 56cm^2

d) area of shaded region = area of ABCD - (area of BCE + area of BEF)

= 112 - (20+56)

= 112 - 76

= 36cm^2
