Question

hanging all around the table,
4. A garden is 120 m long and 85 m wide. It has an inside path of uniform width 3.5 m
all around it. The remaining part of the garden is covered by grass. Find the cost of
covering the garden by grass at 50 paise per square metre.​

Answer 1

Answer:

Step-by-step explanation:

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
