The length of the hypotenuse of a right triangle is 30 m. The length of one leg is 20 cm. Find the length of the other leg. Round your answer to the nearest tenth

I know how to do hypotenuse but this doesn't seem to work out...help please

a^2 + b^2 = c^2

20^2 + b^2 = 30^2

400 + b^2 = 900

b^2 = 500

b = 22.36 = 22.4 cm

So that doesn't really work then does it Ms. Sue - isn't it supposed to be a even number?

I don't think it's supposed to be an even or whole number. Your directions say to round to the nearest tenth.
