Q 9. 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?
Length and breadth of the land are 5m and 4 m.
Side of the square flower bed = 1m
Therefore the area of the bed = 1
So, Area of 5 square flower bed = 5
Area of the and = length breadth
Thus, the area of the remaining part of the land = Area of land - area of the flower bed
= 20 - 5 = 15
