No soy muy buena con álgebra pero te recomiendo esta app que se llama “Symbolab” donde solo tienes que escanear la tarea y te da la respuesta.
Answer:

Step-by-step explanation:
Subtract 13 from 17 to get the length of the base. Then add the 1, 1, and 3 together to get the height. Then you use the area formula for a triangle.
The shortest distance from a point to a straight line is the
measurement of the line segment which connects the point to the straight line.
This line segment should be perpendicular to the line and is thus called the
perpendicular distance.
