Answer 2

The required amount of fence is 120 feet

Given - Length and width

Find - Amount of fence required

Solution - The amount of fence required can be calculated by finding the perimeter. The required length will be equal to the perimeter.

Perimeter can be calculated by the formula -

Perimeter = 2 × (length + breadth)

Keep the values in formula to find the perimeter

Perimeter = 2 × (40 + 20)

Performing addition of values in the bracket

Perimeter = 2 × 60

Performing multiplication to find the perimeter

Perimeter = 120 feet

Hence, 120 feet of fence is required by farmer Bob.
