What is the approximate length of a diagonal of a square with a perimeter of 48 inches?

diagonal length = 12√2 inches

Step-by-step explanation:

If the perimeter of the square is 48 inches, the length of one side is one fourth of that, or 12 inches.  The diagonal creates a 45-45-90 triangle with two 12-in legs; we are to find the length of the diagonal.  Using the Pythagorean Theorem, we get

12² + 12² = (diagonal length)², or 2(12²) =  (diagonal length)²

Taking the square root of both sides, we get:

diagonal length = 12√2 inches

no not all of them.

step-by-step explanation:

some of them have a square base.

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
