Example 1

easy
Find the perimeter of a rectangle with length 88 cm and width 55 cm.

Solution

  1. 1
    Recall the perimeter formula for a rectangle: P=2l+2wP = 2l + 2w.
  2. 2
    Substitute the values: P=2(8)+2(5)=16+10=26P = 2(8) + 2(5) = 16 + 10 = 26.
  3. 3
    The perimeter is 2626 cm.

Answer

P=26 cmP = 26 \text{ cm}
The perimeter of any polygon is the total distance around its boundary. For a rectangle, opposite sides are equal, so we add two lengths and two widths.
