Six square flower beds each of sides 1.5 m are dug on a piece of land 20 m long and 10 m wide. What is the area of the remaining part of land?
Length of the Floor = 20m2
Width of the Floor = 10m2
Area of Floor= 20 x 10 = 200m2
Area of 1 flower bed = Size x Side
= 1.5 x 1.5 =2.25
Area of 6 flower beds = 2.25 x 6 =13.5
So, the area of the remaining part of land
200m2-13.5m2
= 186.50m2
Five square
flower beds each of sides 1.2 m are dug on a piece of land 4.8 m long and
4.2 m wide. What is the area of the remaining part of land?
Area of land = 4.8 × 4.2 =
20.16m2
Area of 1 flower bed = 1.2 × 1.2 = 1.44m2
∴ Area of 5 flower beds = 5×1.44 = 7.2m2
So, the area of the remaining part of land
= 20.16−7.2 = 12.96 m2
