Answer:
[tex]7\sqrt{2}[/tex]
Step-by-step explanation:
Given is a picture of a square with each side = 7 units
Since a square is right angled we have the diagonal bisecting the square into two isosceles right triangles.
Use Pythagorean theorem to get the diagonal length.
Hence diagonal =[tex]\sqrt{7^2+7^2} =7\sqrt{2}[/tex]
Alternate method:
Find the length of the diagonal of a square, multiply the length of one side by the square root of 2: If the length of one side is x, then diagonal will have length as
[tex]x\sqrt{2}[/tex]
