Question

A rectangular lawn of length 50metre and breadth 35 metre is to be surrounded externally by a path which is 2 metre wide .Find the cost of levelling the path at the rate of ₹3 per meter square ​

Answer 1

Answer:

Rs . 10680

Step-by-step explanation:

Inner rectangle Outer rectangle

l = 50m L = 54m

b= 35m B = 39m

Area of the path = Area of outer rectangle - Area of inner rectangle

= ( L x B ) - ( l x b)

= ( 54 x 39 ) - (50 X35)

= 2106 - 1750

= 356 m²

Cost of levelling = 356 x 30

= Rs. 10680
