the perimeter p of a rectangle can be found using the formula p=2(l+w)
where l represents the length and w represents the width. which equation represents the width in the terms of p and l.
a) w=2(p-l)
b)w=p-l/2
c) w=2p-1
d) w=p/2-1
p=2l+2w
p-2l/2=w
p/2-l=w
the answer would be d)
Is this correct? Thanks for checking my work
