Question

6.2 poiThe width of a rectangle is 4 less than half thelength. If l represents the length, which equationcould be used to find the width, w?A. w = {(4 – )c. w = {l - 4B. w = {(l – 4)D. w = 4 - 4uranger

Answer 1

We are told that l is the length of the rectangle. We are told that the widht is 4 less than half the lenght. So, first, we calculate the half of l, which would be

$\frac{l}{2}$

the part that says "4 less than" means that we should subtract 4 from the half of length. So we get

$\frac{l}{2}-4$

now, this expression should be equal to the width , that we'll note as w. So we end up with the equation

$w=\frac{l}{2}-4$
