A rectangular garden is 28 feet long. If you walk diagonally across the garden, you would walk 35 feet. How many feet wide is the garden?

Question

No idea how to do it. Show me the steps and formula, please?

Answer 1

If you draw a diagonal across a rectangle, you get a right triangle.  You can use Pythagorean theorem.

 

28² + (width)² = 35²

 

 

Solve for the width.
