Question

Tyler has a rectangular garden measuring 12m by 20m that he wants to split diagonally from corner to corner using a fence. How long does his fence need to be? Round your answer to the nearest tenth.

Answer 1

23.32 m to the nearest hundredth.

Explanation:

Use the Pythagoras theorem:

The diagonal is the hypotenuse of the right angled triangles formed.

x^2 = 12^2 + 20^2

x^2 = 544

x = 23.32 m.
