Question

Find the area of the following figure.

  1. 9 sq. in    
  2. 13 sq. in    
  3. 4 sq. in    
  4. 15 sq. in    

hintHint:

Divide the figure into separate squares and use the formula of the area of a square.

The correct answer is: 13 sq. in


    Let's divide the figure into two different shapes.
    Suppose the left side is a square P and right side is a square Q.
    At first we will calculate the area of recatngle P.
    Length = 3 in
    Breadth = 3 in
    Area of a square = 3 × 3 = 9 sq. in
    now we will calculate the area of square Q.
    Length = 5 - 3 = 2 in
    Breadth = 3 - 1 = 2 in
    Area of a square = 2 × 2 = 4 sq. in
    Total area of a figure is the sum of the areas of square P and square Q.
    Total area of a figure = area of square P+ area of square Q
    Total area = 9 + 4 = 13 sq. in
    So the total area of figure is 13 sq. in.
