Answer:
7.0711
Step-by-step explanation:
The diagonal of a square of side of length a is a√2.
Here, the length of the square is given as: 5 units.
So, the length of the diagonal is 5√2 units.
But √2 = 1.4142.. (Approx.)
So, the length of the diagonal, d = 5 X 1.4142.
This is equal to 7. 0711.
So, the answer is 7.0711 units.
