Question

a playground 150 M long and 125 M wide has a pathway of with 10 M running breadthwise in the middle find the area of the pathway

Answer 1

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
