Question

A rectangular grassy plot 110 m by 65m has a gravel path2.5 m wide all rounds it on the inside fnd the cost of gravelling path at 80 paisa per square metre

Answer 1

Answer:₹640

Step-by-step explanation:

dimensions of the rectangular grassy plot = 100m × 65m

area of the plot = (100×65)m²

= 6500m²

gravel path is on the inside

so length of the plot without the path = 100 - 2.5 - 2.5

= 95m

breadth of the plot without path = 65 - 2.5 - 2.5

= 60 m

area of the plot without the path = (60 × 95)

= 5700 m²

⇒area of the path = (6500-5700)m²

= 800 m²

rate of cost = 80p/m²

so total cost = ₹(800×80)/100

= ₹640(ans)

hope it helped you!!!!
