Question

A rectangular garden is 95m long 85m wide. A 2.5m path runs all around from it inside. Find the cost of constructing the path at 4 rupee per square meter​

Answer 1

Answer:

length of inner garden = 95m - 2.5m = 92.5m

width of inner garden = 85m - 2.5m = 82.5m

area = lb

        92.5m × 82.5 m

        7,631.25 m^2

area of the garden = lb

                                95m * 85 m

                                  8075 m^2

area of the path = 8075m - 7631.25m

                           443.75 m^2

cost of constructing the path = 443.75 m^2*4

                                                     ₹1775

Answer 2

Answer:

₹3500

Step-by-step explanation:

rupees needed = 4((the sides - 4 corners)/1m^2)

rupees needed = 4((2(95m*2.5m) + 2(85m*2.5m) - 4(2.5m*2.5m))/1m^2)

rupees needed = 4(( 2(237.5m^2) + 2(212.5m^2) - 4(6.25m^2))/1m^2)

rupees needed = 4((475 m^2 + 425 m^2 - 25m^2)/1m^2)

rupees needed = 4(875 m^2/1m^2)

rupees needed = 4(875)

rupees needed = 3500
