Answer:
to ensure 90° corners, the lengths of the diagonal should be the same
Step-by-step explanation:
The Pythagorean theorem can be used to find the expected length of the diagonal. It tells you the square of the diagonal is the sum of the squares of the sides:
d² = (10 ft)² + (6 ft)² = 136 ft²
d = √136 ft ≈ 11.6619 ft ≈ 11 ft 7 15/16 in
The length of each diagonal should be very nearly 11 feet 7 15/16 inches.
