Question

a garden is 120m long and 85 m wide. it has an inside path of uniform width3. 5m all around it. the remaining part of garden is covered bygrass. find the cost of covering the garden by grass at 50paise per square metre​

Answer 1

Answer:

Step-by-step explanation:

HEYA HERE IS YOUR ANSWER..

➡️Length of Garden = 120 metres

➡️Breadth of Garden=85 metres

➡️  It has an inside path of uniform width 3.5m all around it!

➡️  Thus, Length of  portion covered by grass = 120 - (3.5+3.5)

= 120-(7)

= 113 metres

 ➡️  So, Breadth of  portion covered by grass = 85-(3.5+3.5)

=85-7

= 78metres

➡️  Area of  Portion covered by grass = (113×78) = 8814m²

 ➡️   Now, cost of covering the garden by grass at 50 paise per square metre = 8814×0.5

= Rs. 4407

➡️  Therefore, Required cost covering the garden by grass = Rs 4407.

Answer 2

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
