Five square flower beds each of side 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?
We know that,
Area of rectangle = Length × Breadth
It is given in the question that,
Length of rectangle = 5 m
Breadth of rectangle = 4 m
Therefore,
Area of land = Length × Breadth
= 5 × 4
= 20 m2
Also,
Area occupied by 5 flower beds = 5 × (Side)2
= 5 × (1)2
= 5 m2
Therefore,
Area of remaining part = 20 – 5 = 15 m2
