Use the Pythagorean theorem:
The length of the hypotenuse is 6√2 units.
You can look for the number 16 on the x-axis. (bottom line) and put a finger there. Then, look for 19 on the y -axis (left line) and put a finger there. Trace your left finger to the right and your right hand up until they meet. That is (16,19)
The most precise is 4.00 because that is equal to 10.16 cm and that is the most closes to an exact measurment.
337.5 divide 450 by 4 and multiply the product by 3
