A newly constructed rectangular parking lot is $40$ yards long and $25$ yards wide. What is the total perimeter of the parking lot, in yards?

The total perimeter of the parking lot is

130

yards.

To find the perimeter of a rectangle, you must add the lengths of all four sides. Using the formula

P = 2(l + w)

, we substitute the given length (

40

) and width (

25

). Adding those gives

65

, and multiplying by

2

results in a total perimeter of

130

yards.

Identify the shape and the given dimensions.

Shape: Rectangle. Length (

l

) =

40

yards, Width (

w

) =

25

yards.

Understanding the shape and dimensions is necessary to select the correct formula.

Recall the formula for the perimeter of a rectangle.

P = 2l + 2w

P = 2(l + w)

Perimeter is the total distance around the outside of the shape.

Substitute the dimensions into the formula and solve.

P = 2(40 + 25) = 2(65) = 130

Calculating the expression yields the final perimeter in yards.

Perimeter of Rectangles

Instead of using the formula

P = 2(l + w)

, you can simply add all four sides together:

40 + 40 + 25 + 25 = 130
