Problema Solution
A rectangle's length is four times its width. Let w denote the rectangle's width. What polynomial represents the rectangle's area?
Answer provided by our tutors
Let
w = denote the rectangle's width
l = denote the rectangle's length
A rectangle's length is four times its width:
l = 4w
The formula for area of rectangle is A = l*w
A = 4w*w
A = 4w^2 represents the rectangle's area.
