Question

Find the area of the shaded part

  1. 120 sq. m    
  2. 140 sq. mt    
  3. 106 sq. m    
  4. 100 sq. mt    

Hint:

Area of shaded part = Area of outer rectangle - Area of inner rectangle

The correct answer is: 106 sq. m




    Area of shaded part = Area of outer rectangle - Area of inner rectangle
    Area of outer rectangle = length cross timesbreadth = 12 × 10 = 120 sq. m
    Area of inner rectangle = length cross timesbreadth = 7 × 2 = 14 sq. m
    Total area = 120 – 14 = 106 sq. m
