Question

Find the area of the figure

  1. 15 sq. m    
  2. 35 sq. m    
  3. 19 sq. m    
  4. 16 sq. m    

Hint:

Use the formula of the area of a rectangle.

The correct answer is: 19 sq. m


    The figure consists of a verticle rectangle and a horizontal rectangle. 
    At first, we will calculate the area of the verticle rectangle.
    Length of verticle rectangle: 3 m
    the breadth of the verticle rectangle: 5 m
    Area of verticle rectangle = length   cross times  breadth
    = 3 cross times 5
    = 15 m2
    Now we will find the area of a horizontal rectangle.
    Length of horizontal rectangle: ( 7- 3 ) =  4 m
    the breadth of the horizontal rectangle: 1 m
    Area of horizontal rectangle = length   cross times  breadth
    = 4 cross times 1
    = 4 m2
    The total area of figure = area of horizontal rectangle + area of verticle rectangle
    = 15 + 4
    =19 m2

    So the correct option is a.
