the slide at the playground has a height of 6 feet.The base of the slide measured on the ground is 8 feet.what is the length of
NemiM [27]
The formula for finding the length is
{a}^{2}  +  {b}^{2} = {c}^{2}
All we have to do is plug in the numbers.

{6}^{2}  +  {8}^{2}  =  {c}^{2}
36 + 64 = 100

Since 100 =
{c}^{2}
we have to find the square root.

\sqrt{100}  = 10

The length of the slide is 10 feet.
