Question

A rectangular plot 25 m long and 16 m wide has a gravel walk 1.5 meter wide all round it on the outside
. Find the cost of laying the grass on the path at the rate of Rs 5 per square meter
​

Answer 1

1. area is equal to length into breadth that is equals to 25 into 16 is equal to 400
2. that is equals to 400 into 1.5 that is equals to 600

Answer 2

Answer:

Rs 660

Step-by-step explanation:

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

Answer: Rs 660
