Question

A 2m wide flower bed is to be constructed around a football ground of dimension 80m by 60m find the cost of gardening the beds at rate of rs 8 mtr sq​

Answer 1

Answer:

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
