rectangular plot 25 m long and 16 m wide has gravel walk 1.5 metres wide all round it on outside. find cost of laying grass on path at rate of rupees 5 per sq. m​

Answer 1

Answer:

Find the outer length and breadth:

Length = 25 +1.5 +1.5 = 28 m

Breadth = 16 +1.5 +1.5 = 19 m

Find the area of the plot of land with the gravel:

Area = Length x Breadth

Area = 28 x 19

Area = 532 m²

Find the area of the land:

Area = Length x Breath

Area = 25 x 16

Area = 400 m²

Find the area of the gravel:

Area of the gravel = 532 - 400

Area of the gravel = 132 m²

Find the cost of laying the grass:

1 m² = Rs 5

132 m² = 132 x 5

132 m² = Rs 660
