Answer:
x = 3√2 units.
Step-by-step explanation:
Let Δ ABC is a right triangle with ∠ ABC = 90°.
We draw an altitude from B on AC at point D and AD = CD = 3 units.
We have to find x.
Now, BD is the perpendicular bisector of side AC and hence, Δ ABC is a right isosceles triangle.
So, AB = BC = x
And AC = 3 + 3 = 6 units.
So, applying Pythagoras Theorem, AB² + BC² = AC²
⇒ x² + x² = 6²
⇒ 2x² = 36
⇒ x² = 18
⇒ x = 3√2 units. (Answer)
=16.7332
That is one side of the square, so multiply by 4
=66.93
