Let l be the length of the rectangle and w be the width of the rectangle

Give l = 2w

Perimeter of this rectangle = 2w + w + 2w + w = 6w

Perimeter is equal to the perimeter of a square whose area is 1

side of a square whose area is 1 = \(\sqrt{1}\) = 1

perimeter of a square whose side is 1 = \(4 * 1\) = 4

=> Perimeter of this rectangle = 6w = 4

=> w = \(\frac{2}{3}\)

=> l = \(2 * \frac{2}{3} = \frac{4}{3}\)

Area of the rectangle = l * w = \(\frac{4}{3} * \frac{2}{3} = \frac{8}{9}\)

Hence option E

+1 for E.

Let,
Length = L, Width = W, Area = A, Perimeter = P
L = 2W
A = L*W = 2W*W = 2W^2

P = 2L + 2W
P = 6W

Perimeter of of a square whose area is 1
= S^2 = 1 (S= Side of a square)
= S = 1
Then, P = 4*S = 4

Now,
4 = 6W
W = 4/6
A = 2*W^2 = 2*(4/6)^2
A = 2*(16/36)
A = 8/9

Hence, E.
