Answer:
1)
Given:
length of land: 5 m
breadth of land = 2.5 m
length of flower bed = 1 m
To find:
area of remaining land =?
Step-by-step explanation:
Given land is 5 m long and 2.5 m wide.
That means land is in a rectangular shape.
The area of rectangular land is calculated by:
∴ area of land = length × breadth
= 5 × 2.5
= 12.5 m²
Five square flower beds of 1 m length have been made on the rectangular land. Thus the area of square flower beds is calculated by
∴ area of square flower bed = 5 × length²
=5 × 1 × 1 =5 m²
Hence the remaining area of land is calculated by subtracting the area of the square flower bed from the total area of land.
∴ area of remaining land = area of land - area of a square flower bed
= 12.5 - 5
= 7.5m²
Hence, the area of the remaining land is 7.5 m².
2) Figure 2 is has the greatest perimeter.
