Question

The perimeter, p, of a rectangular field can be found using the formula

p = 2l + 2w

where l is the length of the field and w is the width. Which equation could be used to solve for l?

A: l =
B: l =
C: l = p − 2w
D: l = p − w

Answer 1

Solving for L gives us...


\[\Large P = 2L + 2W\]


\[\Large P-2W = 2L\]


\[\Large 2L = P-2W\]


\[\Large L = \frac{P-2W}{2}\]
