Question

In the given figure,ABCD is a rectangle in which AB=60 cm andBC= 40cm. If P,Q,R and S be the mid- points of AD,DC,CB and BA, find the area of shaded region.

Answer 1

I hope the figure is this since you didn't put the figure with this question

Answer 2

Answer:

Step-by-step explanation:

given ab=60cm

bc=40cm

p,q,r,s are the midpoints

therefore

AS=SB= 30cm

BR=CR= 20cm

now join p and r, q and s

in triangle QOR

base=OR=30CM

height= OQ= 20cm

area of triangleQOR= 1/2 ×b×h

1/2×30×20

= 300cm^2

area of the shaded region = 300×4

=1200cm^2
