Question

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?

Answer 1

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.
