Answer:
220m²
Step-by-step explanation:
square shaped park of side 80 m.
two equal rectangular flower beds each of size 10 m by 5m
A/q,
the length of the boundary of the remaining park = area square shaped park of side 80 m/two equal rectangular flower beds each of size 10 m by 5m
=4 x 80 m - 2 x 10m x 5m
=320m²- 100m²
=220m²
suppose it is correct
The answer to the question could be:-
Given,
Side of square park = 80 meter
Length of two same flower beds = 10 meter
Breadth of two same flower beds = 5 meter
Perimeter of the park without including the flower beds = ?
The perimeter of the park without including the flower beds can be obtained by subtracting the perimeter of the two flower beds from perimeter of the park including the flower beds. The solution to the above question is:-
Perimeter of a square = 4 * Side
Perimeter of the park including the flower beds = 4 * 80 meters
= 320 meters
Perimeter of rectangles = length * breadth
Perimeter of the two flower beds = 10 * 5
= 50 meters
Perimeter of the park without including the flower beds = 320 - (50 + 50)
= 320 - 100
= 220 meters.
