Draw line segments to form triangle \( A B C \) Segment \( A C \) measures 5 units. Find the perimeter and area of triangle \( A B C \). \( P= \)

Use lactoring to solve the quadratic equation. Check by substitution or by using a graphing utility and identifying \( x \)-intercepts. \[ x^{2}-25=0 \] The solution set is \( \} .21 \) (Use a comma to separate answers as needed. Type repeated roots only once.)
