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:

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