Answer:
1) 160 sq.cm
step by step solution:
Length of big rectangle = 24 cm
Breadth of big rectangle = 20cm
Area of big rectangle = l×b
= 24×20
= 480 sq.cm
Length of small rectangle=24-(2+2)=20cm
Breadth of small rectangle=20-(2+2)=16cm
Area of small rectangle = l×b
=20×16= 320 sq.cm
Area of shaded= Area of big - Area of small
region. rectangle. rectangle
= 480 sq.cm - 320 sq.cm
= 160 sq.cm
