प्रश्न
Five square flower beds each 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?
उत्तर
Area of flower square bed = 1 × 1
= 1 m2
Area of 5 square beds = 1 × 5
= 5 m2
Area of land = 5 × 4
= 20 m2
Remaining part of the land = Area of land – Area of 5 square bed
= 20 – 5
= 15 m2
∴ The remaining part of the land is 15 m2.
