To calculate the total length of the rope needed to fence the field, we need to find the perimeter of the rectangle. The formula for the perimeter of a rectangle is:

\text{Perimeter} = 2 \times (\text{Length} + \text{Width})

Given:

Length = 220 m

Width = 140 m

\text{Perimeter} = 2 \times (220 + 140) = 2 \times 360 = 720 \, \text{m}

The farmer will need 720 met

ers of rope.

Hello,

To find the total length of rope the farmer needs, we need to calculate the perimeter of the rectangular field. The formula for the perimeter of a rectangle is:

Perimeter=2×(Length+Width)

Given:

• Length = 220 m
• Width = 140 m

Substituting the values into the formula:

Perimeter=2×(220+140)=2×360=720m

So, the farmer needs 720 meters of rope to fence his field.
