Question

Joel is laying pipe for a sprinkler system before he plants his lawn. The lawn is a rectangle, 15 feet long and 8 feet wide. He needs to lay a piece of pipe that will run along the diagonal of the lawn. It will divide the area of the lawn into two right triangles. What will be the length of the pipe? A. 120 feet B. 17 feet C. 289 feet D. 23 feet

Answer 1

This is a simple Pythagoras' theorem problem. If the length of the right angled triangle is 15ft and its width is 8ft, then its hypotenuse (x, the diagonal or the length of the pipe in this case) will be:
$x = \sqrt{ {8}^{2} + {15}^{2} } \\ x = \sqrt{64 + 15} \\ x = \sqrt{289} \\ x = 17$
Therefore, your answer is B. The length of the pipe will be 17 feet.
