Question

Five square flower beds each of sides 1 m are dug on a piece of land 5 m long and 4 m wide. What is the area of the remaining part of the land?

Answer 1

Side of square bed = 1 m 

Area of square bed = side x side = 1 m x 1 m = 1 m² 

Area of 5 square beds = 1 x 5 = 5 m² 

Now, Length of land = 5 m and breadth of land = 4 m 

Area of land = length x breadth = 5 m x 4 m = 20 m² 

Area of remaining part = Area of land – Area of 5 flower beds 

= 20 m² – 5 m² = 15 m²
