एक आयताकार खेत की लंबाई 20 मीटर चौड़ाई 10 मीटर है और इसके चारों तरफ तार का घेरा बनाना हो तो कुल कितना तार लगेगा.

♕︎Answer♕︎

उसके परिमाप के बराबर का तार लगवाना होगा

परिमाप= २(लंबाई+चौड़ाई)

=२(२०+१०)

६०m^२

Answer 2

Approximately you need around 122.8 metres of wire to encircle the rectangular field.

• Calculating the rectangle's perimeter and adding the length of wire needed to form a full circle can help us determine how much wire is needed to create a circle around a rectangular field.

• The following formula may be used to get the rectangular field's perimeter:

• Perimeter is equal to 2 x (length + breadth).

• Radius = 2 x (20 + 10)

• Radius = 2 x 30

• 60 metres are the perimeter.

• Finding the circle's circumference is necessary to determine the length of wire needed for it, and this measurement may be determined as follows:

• Radius = 2 times the circumference

• As the circle's diameter will be equal to the rectangular field's length, the radius will be equal to half that length, which is:

• Radius: 10 metres (20 divided by 2)

• Now, we can use the formulas below to get the circle's circumference:

• Circumference is equal to 2 x x 10 and 20 x x.

• Using = 3.14 as a rough estimate, we obtain:

• 20 times 3.14 equals a circumference of 62.8 metres.

• The sum of the rectangle's perimeter and the circle's diameter is the total amount of wire needed to form a circle around the rectangular field:

• The total length of the wire equals the circle circumference plus the rectangle's perimeter

• Total wire length = 60 + 62.8

• 122.8 metres of wire are used in total.
