Answer: The cost is Rs 370.88
Step-by-step explanation:
Find the length of the park:
Given that one side of the length is a wall, so the perimeter of the fence is made up by 3 sides only.
Perimeter = Length + breadth + breadth
15.5 = Length + 3.45 + 3.45
15.5 = Length + 6.9
Length = 15.5 - 6.9
Length = 8.6 m
Find the area:
Area = Length x Breath
Area = 8.6 x 3.45 = 29.67 m²
Find the cost:
1 m² = Rs 12.50
29.67 m² = 12.50 x 29.67 = Rs 370.88
