Question

If the diagonal of a square is 11.3 what is the perimeter

Answer 1

Answer:

Perimeter is 31.9 units.

Step-by-step explanation:

Given that the diagonal of a square is 11.3 units. We have to find the perimeter of square.

Let the side of square is a units.

As, diagonal of square is $a\sqrt2$

⇒ $11.3=a\sqrt2$

⇒ $a=\frac{11.3}{\sqrt2}=7.99030662741\sim7.9$

Hence, side of square is 7.99 units.

Now, Perimeter=4a=31.96 units

Hence, Perimeter is 31.9 units.
