Question 440712: Please help me solve this equation:
A fence around a square garden has a perimeter of 20 feet. Find the length of the diagonal of the garden to the nearest foot.
Answer by Euler(11)   (Show Source):
You can put this solution on YOUR website! Okay so 20 feet perimeter means that each side is 5 feet long. To find the diagonal, take two sides and apply the Pythagoras Theorem. So,
5^2+5^2=diagonal^2
25+25=diagonal^2
50 =diagonal^2
Taking square root on both sides, we get:
7.071=diagonal
Since you want the answer to the nearest foot, you get 7 feet. :)
