Question

(g) A rectangular park is 55 m by 25 m. A path 2.5 m wide is built all around it inside it.
Find the cost of grassing the remaining part of the park @ 7 60
per
m?​

Answer 1

Answer:

Length of the lawn = 50 m

Breadth of the lawn = 35 m

Area of the lawn = (50 × 35) m²

= 1750 m²

Length of lawn including the path = [50 + (2 + 2)] m = 54 cm

Breadth of the lawn including the path = [35 + (2 + 2)] m = 39 m

Area of the lawn including the path = 54 × 39 m² = 2106 m²

Therefore, area of the path = (2106 - 1750) m² = 356 m²

For 1 m², the cost of turfing the path = $ 3

For 356 m², the cost of turfing the path = $3 × 356 = $1068
