Question

The perimeter of a square is 36 inches. Find the length of a diagonal. Round your answer to the nearest tenth.

Answer 1

Answer:

12.7

Step-by-step explanation:

The diagonal formula is x*sqrt(2) with x being one side length.

To find the side length divide the perimeter by 4.

That gives us 9.

Then, all you have to do is multiply that by the square root of 2 and then round.

Answer 2

Answer:

36/4 = 9

9 inch per side lol

9 rad 2 will be diagonal because of the 45 45 90 type triangle
