Find the perimeter of a rectangular area with a length of 13 inches and
a width of 7 inches.
Calculate with and without distribution
there are two lengths and two widths, so the perimeter is
13+7+13+7 = 40
2(13+7) = 40 inches
P = 2L + 2W
P = ?
To find the perimeter of a rectangle, you need to add up all the sides. In this case, we have a rectangle with a length of 13 inches and a width of 7 inches.
To calculate the perimeter without using distribution, you can directly add up all the sides of the rectangle.
Perimeter = 2 * (length + width)
= 2 * (13 inches + 7 inches)
= 2 * 20 inches
= 40 inches
So, the perimeter of the rectangular area is 40 inches.
To calculate the perimeter using distribution, you can distribute the multiplication to each side of the rectangle.
Perimeter = 2 * length + 2 * width
= 2 * 13 inches + 2 * 7 inches
= 26 inches + 14 inches
= 40 inches
So, the result is the same - the perimeter of the rectangular area is 40 inches, regardless of whether you use distribution or not.
