Answer:
[tex]52m[/tex]
Step-by-step explanation:
We can use the Pythagorean theorem to find the length of the diagonal since drawing a diagonal across a rectangle results in two right angle triangles.
Length of diagonal [tex]= \sqrt{20^2+48^2}[/tex] (The length of the diagonal can be thought of as the hypotenuse of one of the right angle triangles)
[tex]=\sqrt{2704}[/tex]
[tex]=52 m[/tex]
∴ The length of the diagonal is [tex]52 m[/tex]
Hope this helps :)
