OA is B

2(l+b)=6w
so l+b=3w
if one of the sides is 1/2w then the longer side is 2.5w, when multiplied gives 2.5w^2/2, the only answer that matches the fractional value is B.

2 * (l+b) = w
b = 5w/2 ; l= w/2

area ; 5 w^2/4
IMO B

2(l+b) = 6w
l+b = 3w

l=w/2

b will be now 5w/ 2

Area of a rectangle = l * b
=>$$\frac{5w^2}{4}$$
