Using Pythagoras theorem, we can calculate the length of the diagonal (d) of the rectangle swimming pool:
d^2 = w^2 + l^2
d^2 = 21^2 + 50^2
d^2 = 441 + 2500
d^2 = 2941
Taking the square root of both sides:
d = √2941
d ≈ 54.2 metres
Therefore, the length of the diagonal of the rectangle swimming pool is approximately 54.2 metres.
A rectangle swimming pool is 21metres wide and 50metres long.calculate the length of the diagonal to 1 decimal please (Pythagoras theorem)
