Question

Use the formula P = 2l + 2w. Find the perimeter of a rectangle with a length of 12.9 ft and a width of 19.3 ft.

64.4 ft
68.4 ft
66.7 ft
61.7 ft

Answer 1

Welp, it can't get any easier. Now, they give you the value for l (length which is 12.9) and the give you the value for w (width which is 19.3)

Now, you'd just plug them in. So

P = 2(12.9) + 2(19.3)
=25.8+38.6
=64.4ft
