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 be 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 that diagonal piece of pipe?
**Weegy:** AB=15 Feet
BC=8 Feet
AC=Diagonal, [ that is to be found out.
Use phosphorous theorem :
AB^2 + BC^2 = AC^2
15^2 + 8^2 =AC^2
225 + 64 =AC^2
AC^2 = 289
AC=Square Root [289]
AC = 17 Feet.
17 Feet will be the length of that diagonal piece of pipe.
