What is Perimeter?
Perimeter is the distance around a shape. A rectangle is a four-sided figure with two pairs of parallel sides. The perimeter of a rectangle is the distance around the outside of the figure. To find the perimeter of a rectangle, you simply add up the lengths of all the sides.
A rectangle is a shape with four straight sides and four right angles. The perimeter of a rectangle is the distance around the outside of the shape. To calculate the perimeter of a rectangle, you simply add up the length of all four sides.
Properties of a Rectangle
A rectangle is a four-sided figure with two pairs of parallel sides. The length of a rectangle is measured from one corner to the other corner, and the width is measured from one edge to the other edge. Rectangles have four right angles.
Formula Perimeter of Rectangle
A rectangle’s perimeter is the sum of the lengths of its four sides. The formula for perimeter is P = 2L + 2W, where L is the length of a side and W is the width.
For this problem, let’s find the perimeter of a rectangle with a length of 4 feet and a width of 3 feet.
P = 2L + 2W
P = (2)(4) + (2)(3)
P = 16 + 6
P = 22
