Question

ABCD is a rectangle .calculate its shaded area .​

Answer 1

Answer:

Area of trapizium = 1/2 (a+b) × h

= 1/2(4+8)×6

= 1/2×12×6

= 36 cm^2

Area of rectangle= l×b

= 12×16

=192 cm^2

Area of shaded figure = (area of rectangle)- (area of trapizium)

= 192-36

= 156 cm^2

hence area of its shaded figure is 156 cm^2
