Trig
Use Lemma sin m + sin n = 2sin(m+n/2)cos(m-n/2) cos m + cos n = 2cos(m+n/2)cos(m-n/2) We get (sin m +sin n)/cos m + cos n) = sin(m+n/2)/cos(m+n/2) = tan m+n/2)

Algebra
Okay, so your basic equation for perimeter is P= 2l + 2w So if your l=4w, then you're just going to substitute your values-> P=2(4w)+ 2w Hope this helps XD
