Answer:
1. 12 sq cm
2. 33 sq cm
3. 300 sq inch
Step-by-step explanation:
1.Area of shaded region = area of big square - area of small square
= 4*4-2*2
=16-4
= 12 sq cm
2. Total area = area of square(of side 5) + area of rectangle (of side 4 and 2)
= 5*5+4*2
=25+8
= 33 sq cm
3. Total area = area of rectangle (of side 10 and 20) + area of right angle triangle (of base 10 and height 20)
= 10*20+1/2*10*20
= 200 + 5*20
= 200 + 100
= 300 sq in

Answer:
1. Side of outer square = 4cm
Area of outer square = 4cm × 4cm = 16cm^2
Side of inner square = 2cm
Area of inner square = 2cm × 2cm = 4cm^2
Area of shaded portion = 16cm^2 - 4cm^2 = 12cm^2
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2.Side of square = 5cm
Area of square = 5cm × 5cm = 25cm^2
Length of rectangle = 4cm
Breadth of rectangle = 2cm
Area of rectangle = 4cm × 2cm = 8cm^2
Area of figure = 25cm^2 + 8cm^2 = 33cm^2
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3.Area of rectangle = 10inch × 20inch = 200sq inch
Base of triangle = 10 inch
Height of triangle = 10inch + 10inch( opp. side of rectangle ) = 20inch
Area of triangle = 1/2 × 10 × 20 = 100 sq inch
