Perimeter of a Square or a Rectangle
The perimeter of a square is the total length of the four equal sides of the square.
If the side of a square is s, the perimeter of the square is
= 4 × s = 4 s
The perimeter of a rectangle is the total length of the two lengths and two widths of the rectangle.
If the length and width of a rectangle are l and w, then its perimeter
= 2(l + w) units
If the side of a square is 8 m, find the perimeter of the square
Side length of the square = 8 m
The perimeter of the square = 4 × 8 = 32 m
If the length and width of a rectangle are 8 and 4 units, then find its perimeter.
Length and width of the rectangle are 8 and 4 units
Perimeter of rectangle
= 2 (l + w) = 2(8 + 4)
= 2 × 12 = 24 units
