Concept
Area of the shaded part
= Area of the outer square - Area of the inner square
Next,
Area of the outer square = Length x Length = 5 x 5 = 25
Area of the inner sqaure = Length x Length = 2 x 2 = 4
Final answer
The area of the shaded part = 25 - 4
= 21 inches square
two 5 in by 1.5 in and two 2 in by 1.5 in
1.5
2 in and 5 in
