Question

The perimeter p of a rectangle is related to the length l and width w through the equation p=2l+2w. determine the width in terms of the perimeter and length.

Answer 1

To find the equation for width in terms of length and perimeter, we need to solve for w in the equation for perimeter:
$p=2l+2w$
$p-2l=2w$
$\frac{1}{2}p-l=w$
