Question

Calculate the area of the shaded region in the figure given below:

Answer 1

area of big rectangle=lb=27×43=1161m^2
length of small rectangle=43-(1.5+1.5)=43-3=40m
breadth of small rectangle=23-(1+1)=23-2=21m
area of small rectangle=40×21=840m^2
area of shaded region=(1161-840)m^2=321m^2
hope it helped
if helped mark it brainliest thankyou.......
