उत्तर
A square shaped park ABCD of side 100 m has two equal rectangular flower beds each of size 10 m × 5 m (Figure). Length of the boundary of the remaining park is 400 m.
Explanation:
In order to find the length of the boundary of the remaining park, we add two flower beds each of length 10 m and breadth 5 m, then remaining park is shown below
Now, length of the boundary of the remaining park = Perimeter of remaining park
= (90 + 5 + 10 + 95 + 90 + 5 + 10 + 95) m
= 400 m
