Question

A garden is 120 m long and 85 m wide. It has an inside path of uniform width 3.5
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:

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

Answer.

Step-by-step explanation:

Answer 2

Answer

Step-by -step

The lenge of the Outer rectangle = 120m

The breadth of the Outer rectangle = 85m

The Uniform width of the inside path is 3. 5m all around it.

The lenght of the inner rectangle = 120 -7 = 113m

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

Area of inner rectangle = l × b

=113×85m²

=8814m²

we have to find the cost of Covering,

we know that ₹ 1 = 100 paisa then 50 paisa = 0•5 rupees.

The total cost of Covering garden by grass = 0•5 ×8814 = ₹ 4407

Hence,the total cost of Covering the field the grass is ₹ 4407
