Question

a garden is 120 M long and 85 metre wide it has an inside path of uniform width of 3.5 all around it find the cost of levelling the path at at rupees 1.25 per square meter and watering the remaining portion of the garden at 50 paise per square metre ​

Answer 1

Answer:

Solution:-

Let the outer rectangle be ABCD and the inner rectangle be abcd. 

Length and Breadth of the outer rectangle = 120 meter and 85 meter.

The uniform width of the inside path is 3.5 meter,

So, the length of the inner rectangle = 120 - 7 = 113 m 

and the breadth of the inner rectangle = 85 - 7 = 78 m

The area of the inner rectangle = 113 × 78 = 8814 m²

Cost of covering the garden by grass = Rs 0.5 per square meter.

The total cost of covering the garden by grass = 0.5 × 8814

= Rs 4407
