Step-by-step explanation:

Given: diagonal = 13 2–√ inches

In a square all it’s sides are equal to each other.

If you divide a square into two equal triangles (use of a diagonal) you will have two equal isosceles right triangles.

Of course you know that an isosceles right triangle has two 45 ∘ and one 90 ∘ angles.

To find the side you can use sine or cosine of 45 ∘ .

sin(45) = x132√

(13 2–√) x (sin(45)) = 13 inches

Each side is 13 inches.

A square has 4 sides: 13 x 4 = 52 inches

>>>>>>>>>So: the perimeter of this square is 52 inches.
