Question

A rectangular lawn measuring 50 metres by 36m is surrounded externely by a path which is 2 metres wide find the area of the path and the cost of levelling of the path at 3.25m2​

Answer 1

so, => L = 50 + 2 + 2 = 54 m. => B = 36 + 2 + 2 = 40 m. Area of path 360 m²

Answer 2

Answer:

The original area :

Original length× Original Breadth

= 50×36

= 1800 m² .

Now,

New Area :

New length = 50+2

                    = 52 m

New Breadth = 36+2

                       = 38 m

New Area = 52×38

                 = 1976 m² .

Area of path = New Area - Original Area

                      = 1976-1900

                      = 76 m

Cost of leveling 1 m² = ₹ 3.25

Cost of leveling 76 m² = ₹3.25×76

                                       = ₹ 247
