Perimeter and Area
Perimeter of an equilateral triangle = 3 × length of a side
Perimeter of a square = 4 × length of a side
In general, perimeter of a regular closed polygon = Number of sides of the polygon × length of each 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)
= 5 × (4 × side)
= 5 × [(4 × 50) m]
= 1…
