If the sides of a square measure 9sqrt3 units, then find the length of the fishbowl.
OlgaM077 [116]

The length of the diagonal of the square is 22.05 units

<h3>How to find the diagonal of a square?</h3>

A square have all its sides equal to each other.

Therefore, using Pythagoras theorem,

c² = a² + b²

c² = (9√3)² + (9√3)²

c² = 81 × 3 + 81 × 3

c² = 243 + 243

c² = 486

square root both sides

c = √486

c = 22.045407685

c = 22.05 units
