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? TIPS Firstly, find the area of five square flower beds and piece of land separately. Then, area of the remaining part of the land will be obtained by subtracting the area of five beds from area of land.

Answer:

Given, length of the piece of land = 5 m and breadth of the piece of land = 4 m Area of the piece of land \[=Length\times Breadth=5m\times 4m=20sqm\] Given, side of one square flower bed = 1 m \[\therefore \] Area of one square flower bed = Side \[\times \] Side \[=(1\,m\,\,\times \,\,1m)=1\,sq\,m\] Then, area of 5 such flower beds = 5 \[\times \] Area of one square flower bed \[=5\times 1sq\,m=5sqm\] Now, area of the remaining part of land = Area of the piece of land ? Area of 5 square flower beds \[=\text{ }(20\,-5)sq\text{ }m=15\text{ }sq\text{ }m\] Hence, the area of the remaining part of the land is 15 sq m.
