Answer:
35.35 cm
Step-by-step explanation:
[tex]Side = 25 cm\\\\Diagonal = ?\\[/tex]
Look at the image ; notice we have a right angle triangle ?
So , we can derive :
Hypotenuse = ?
Opposite = 25
Adjacent = 25
[tex]Pythagoras \:Theorem ;\\Hypotenuse^2 =Opposite^2+Adjacent^2 \\\\x^2 = 25^2 +25^2\\x^2 = 625+625\\\\x = \sqrt{1250}\\ \\\\x = diagonal = 25\sqrt{2} \\= 35.35[/tex]
