Answer 1

Step-by-step explanation:

Question :-

a path 3 metre wide runs along the inside of a rectangular plat of dimensions 30 metre × 24 metre find the cost of levelling the path at the rate of rupees 32 per square metre

To find :-

cost of levelling the path at the rate of rupees 32 per square metre

Solution:

Length of outer rectangle =30m

Breath of outer rectangle = 24m

Area= 30×24= 720m²

Length of inner rectangle = 30-3=27m

Breadth of outer rectangle = 24-3=21m

Area= 27×21=567m²

Area of the path = 720-567= 153m²

Cost for levelling 1m²= Rs32

Cost for levelling 153m²= Rs4896

So, Rs4896 is your answer

Hope this helps
