Question

A farmer has a square field of side 240m. He wants to fence it with 3 rounds of rope. What is the total length of rope he must use?​

Answer 1

Answer:

perimeter of square- 4×side

so,= 4×240 = 960m

to fence the field 3rounds of rope

=960×3 =2880m

=so he need 2880m length of rope

Answer 2

Given :-

• A farmer has a square field of side 240m
• He wants to fence it with 3 rounds of rope.

To Find :-

• The total length of rope he must use

Solution :-

❏ As we know that, Fencing is done on the boundary. So, we will find the Perimeter of Square Field which is given by 4 × side.

⟾ Rope Used in 1 round = Perimeter of Field

• Perimeter of Field = 4 × side
• Perimeter of Field = 4 × 240
• Perimeter of Field = 960m

Now,

⟾ Rope Used in 1 round = 960m

• Rope used in 3 round = 960 × 3
• Rope used in 3 round = 2880m

Thus , 2880m of rope will be used to fence the Field 3 times.

Formulas Related to Square :

• Perimeter = 4 × Side
• Area = Side × Side
• Side of Square = √Area
• Diagonal = √2 × Side
• Area = ½ × (Diagonal)²
• Area = (Perimeter ÷ 4)²
