Solution
The correct option is A 10 Let's get the dimensions:
Area of rectangle on the top = Area of rectangle on the bottom
= length × breadth
= 4 × 1 sq. ft
= 4 sq. ft
So, total area of the two rectangles is:
= 4 × 2 sq. ft
= 8 sq. ft
Area of the rectangle in the middle
= length × breadth
= 2 × 1 sq. ft
= 2 sq. ft
∴ Total area of the figure is:
= 8 sq. ft + 2 sq. ft
= 10 sq. ft
