Question 1162474
p = perimeter of the rectangle.
x = the length
y = the width.
p = 2 * (x + y)
that means the perimeters is equal to 2 times the sum of the length and the width.
x = 30m
y = 15m
p = 2 * 45m = 90m
here's a reference on perimeter of a rectangle.

the references uses l for the length and w for the width.
my formula would then be:
p = perimeter of the rectangle
l = length
w = width
p = 2 * (l + w)
this is the same as p = 2l + 2w.
i just factored out the 2.
