Question

A Path 2.5m Wide is to be constructed outside a rectangular park of length 45 m and breadth 30m. find the cost of construction of path at the rate of ₹150 per m square​

Answer 1

Step-by-step explanation:

Area of the rectangular park= 45×30= 1350 sq.m

Including the path

length=45+2.5+2.5 m = 50 m

breadth=30+2.5+2.5 m = 35 m

Area of the park along with the new path= 50×35 = 1750 sq.m

Area of the path=1750-1350 sq.m=400 sq.m

Cost of Construction= Rs. (400×150) =Rs. 60,000

Answer 2

Answer

Rupees = 27712.5

Step-by-step explanation:

Area of inside part = 45m × 30m

= 1359m²

Area of inside part = (45m+2.5m)×(30m + 2.5m)

= 47.5m × 32.5m

= 1543.75

Area of path = 1543.45 - 1359

= 184.75

A-T-Q,

Rate of construction of path = 150 × 184.75

= 27712.5
