Answer 1

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

Answer: The cost is Rs 370.88
