Four square flower beds of side 1 m 50 cm are dug on a rectangular piece of land 8 m long and 6 m 50 cm wide. What is the area of the remaining part of land?
Answer
Given:
Length of the land = 8 m
Breadth of the land = 6 m 50 cm = 6.5 m
Side of each flower bed = 1 m 50 cm = 1.5 m
Number of flower beds = 4
Area of the rectangular land = length × breadth
= 8 × 6.5 sq. m
= 52 sq. m
Area of one square flower bed = side × side
= 1.5 × 1.5 sq. m
= 2.25 sq. m
Area of 4 flower beds = 4 × 2.25 = 9 sq. m
Area of the remaining part of land = Area of land - Area of 4 flower beds
= 52 - 9
= 43 sq. m
Hence, the area of the remaining part of land is 43 sq. m.
