Answer:

Measure the diagonals, they should be 5 feet (3,4,5 triangle).

Step-by-step explanation:

As a more general answer, the diagonal measurements of ANY rectangle will be equal. You can calculate the correct measurement using A^2 + B^2 = C^2. A and B are the lengths of the sides and C is the length of the diagonals.
