Surely the width is 3x + 5
If you have a rectangle of length x and width w
then area is wx = 3x^2 + 5x
divide both sides by x to find w

The formula to find area of a rectangle is length x breadth
Taking length as "x"
we get area = x into width
substitute area value for that given, we get
3x^2 + 5x = xw (where w stands for width)
divide through out by x, we get
3x + 5 = w
Hence the width of the rectangle is three times its length plus 5

they are asking you to factor the expression. divide the area by the length to get width because area = L*W
so you get x(3x+5)
the rectangle is three times its height plus five units wide
3x^2 +5x= (x)(w)
divide by height x
3x + 5 = w

w=6x+5
verify with your teacher
