Eq1: L*W = 384yds^2.

@l + 2W = 120

Divide both sides by 2:

L + W = 60.

Eq1: L * W = 384.

Eq2: L + W = 60.

Solve for L in Eq2:

L = 60 - W.

In Eq1, substitute 60-W for L:

(60-W)W = 384

-W^2 + 60W -384 = 0.

Solve using Quadratic Formula and get:

W = 7.28 or 52.7.

Substitute 7.28 for W in Eq1:

7.28*L = 384

L = 52.7 Yds.

Solution:

L = 52.7 Yds.

W = 7.28 Yds.

To form 2 equal rectangular sections:

L = 52.7 Yds.

W = 7.28/2 = 3.64 Yds.

OR

L = 52.7 / 2 = 26.35 Yds.

W = 7.28 Yds.
