The length of a rectangle is four times it's width. if the area of the rectangle is 144 cm, find its perimeter

The width is 6

the length is 24

so the perimeter is

the answer is 60

good luck

If i'm correct the answer is $15.97

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
