Pythagorean theorem
25^2 = x^2 + x^2
so 625 = 2x^2
312.5 = x^2
17.68 = x

Answer:

$\tt x=\pm5\sqrt{2}$

Step-by-step explanation:

$\tt x^2 - 25 = 25$

$\tt x^2-25+25=25+25$ (Add 25 to both sides)

$\tt x^2=50$ ( Take square of both sides)

$\tt x=x=\sqrt{50},\:x=-\sqrt{50}$

$\tt x=\pm5\sqrt{2}$

Let w be the width.

2(2w) + 2w = 54.

4w+2w = 54
6w=54.
w=9
So length equals twice that...I think you can solve that on your own. xD
