Arleth saw a rectangular tennis court that has a perimeter

of 24m and a width of 4m. What is the length, in meters, of

the tennis court?

8 meters

Step-by-step explanation:

Draw a rectangle and label the two ends of the rectangle with the width of 4. Now, you will notice you have two sides left of equal length, which represents your length. The formula for perimeter of rectangles is 2l + 2w = P, in which w is the width and l is the length. Plug your known values into the equation and solve for l.

2l + 2 (4) = 24

2l + 2 (4) - 2 (4) = 24 - 2 (4)

2l = 24 - 2 (4)

2l = 16

2l/2 = 16/2

l = 8

8 meters is the length of the tennis court.
