for the above rectangle:
Let us suppose width=w then length=w+4
perimeter= 2(w+w+4)=96
solve for w; w=22 this gives length=26
area=l*w=26*22=572(E)
Let us suppose width=w then length=w+4
perimeter= 2(w+w+4)=96
solve for w; w=22 this gives length=26
area=l*w=26*22=572(E)

572 is the correct answer
l=26
w=22
a= l*w
=572
l=26
w=22
a= l*w
=572
