Perimeter and Area

Perimeter of an equilateral triangle = 3 × length of a side
Perimeter of a square = 4 × length of a side

Example:

If a farmer wants to fence a square field of length 50 m with 5 rounds of wire then what is the length of the wire required?

Solution:

Length of wire required = 5 × (perimeter of square field)
