A, D, E
Step-by-step explanation:
The perimeter is all of the sides added together
So, since a rectangle has 2 pairs of parallel congruent sides, or 2l and 2w, anything that would result in 2l+2w would be correct.
A, l+w+l+w=2l+2w
B, l*w cant be simplified more
C, 2*l*w would end up with 2l*w due to pemdas
D, 2(l+w)=2l+2w by distribution
E, (2*l)+(2*w)=2l+2w
