Question

A rectangular grassy lawn measuring 50m by 30m is to be surrounded
externally by a path, which is 3.5m wide. Find the cost of the leveling the path at
the rate of Rs 5 per sq. m

Answer 1

Step-by-step explanation:

length of lawn = 50m

breadth of lawn = 30m

Area = l × b

= 50 × 30

= 1500m²

Now ,

Length of lawn with path = 50 + 3.5 + 3.5 = 57 m

Breadth of lawn with path = 30 + 3.5 + 3.5 = 37m

2nd Area = 57 × 37 = 2109m²

Area of path = 2109 - 1500

= 609m²

cost of leveling of path = 5 × 609

= Rs. 3045
