answer:
52
step-by-step explanation:
- we can use the 45-45-90 triangle theorem for this: x, x, x

this is because this is a square
- squares have two sides of the same length, and the diagonal is different
- the x's stand for the sides, whereas the x
stands for the diagonal
x
= 26
x = 13
- now multiply this by 4 because this is the length of one of the sides of the square. in order to find the perimeter we have to either add this four times or multiply by 4
13
X 4 = 52
