Answer:
Step-by-step explanation:
Given:BEFC is a quarter circle.
Thus,BC=BE=radius of a circle
BC=BE=DC=4.2cm...(Given)
Now,AB=AE+BE
=2+4.2
=6.2cm
ABCD is a trapezium AB||DC and
Angle ABC=90
Thus,area of trapezium
ABCD=AB+CD/2 *BC
=6.2+4.2/2 *4.2=21.84cmsq.
Area of quarter circle =π(BC)sq./4
=22/7*(4.2)sq./4
=22/7*17.64/7*4
=13.86cmsq.
Thus,area of shaded region
=(21.84-13.86)cmsq.
=7.98cm sq..
