Question 204201

Let the length of the rectangle be L

Since its width is 5 less than its length, then width = L – 5


Now, since its perimeter = 50, then 2(L) + 2(L – 5) = 50


a)	2L + 2L – 10 = 50 (equation of perimeter, in terms of L, its 	length)


b)	2L + 2L – 10 = 50
	4L = 60
	L  =  15


Since L, or its length is {{{highlight_green(15)}}}”, then its width is (15 - 5), or {{{highlight_green(10)}}}”
