Answer:
The length of the diagonal is 8.6 units .
Option (C) is correct.
Step-by-step explanation:
As given
The length of a rectangle is 7 units and its width is 5 units.
Now by using the pythagorean theorem
Hypotenuse² = Perpedicular² + Base²
Now as shown in the figure given below.
AC² = AD² + DC²
As
AD = 5 units
DC = 7 units
Put in the above
AC² = 5² + 7²
AC² = 25 + 49
AC² = 74
[tex]AC = \sqrt{74}[/tex]
AC = 8.6 units
Therefore the length of the diagonal is 8.6 units .
Option (C) is correct.
