To find the perimeter of a rectangle, you add up the lengths of all four sides. Since opposite sides of a rectangle are equal, the perimeter formula simplifies to:
Perimeter=2×(Length+Width)\text{Perimeter}=2\times (\text{Length}+\text{Width})Perimeter=2×(Length+Width)
where "Length" is the length of the rectangle and "Width" is the width (or breadth) of the rectangle
Steps to Calculate Perimeter:
- Measure the length (l) of the rectangle.
- Measure the width (w) of the rectangle.
- Add the length and width: l+wl+wl+w.
- Multiply the sum by 2: 2×(l+w)2\times (l+w)2×(l+w).
Example:
If a rectangle has a length of 14.5 feet and a width of 7.5 feet, the perimeter is:
2×(14.5+7.5)=2×22=44 feet2\times (14.5+7.5)=2\times 22=44\text{ feet}2×(14.5+7.5)=2×22=44 feet
This means the total distance around the rectangle is 44 feet
. This formula works because a rectangle has two lengths and two widths, so the perimeter is the sum of all four sides: l+w+l+w=2l+2w=2(l+w)l+w+l+w=2l+2w=2(l+w)l+w+l+w=2l+2w=2(l+w)
. In summary, to find the perimeter of a rectangle, use:
Perimeter=2×(Length+Width)\boxed{\text{Perimeter}=2\times (\text{Length}+\text{Width})}Perimeter=2×(Length+Width)
