11th grade geometry: triangle sba has coordinates s(15,-8),b(-2,21), and a(0,0). if the height of the triangle for the corresponding base sb is 8.89 units, then determine the perimeter and area of triangle sba. round your answer to the nearest unit

The perimeter is 72 units and the area is 149 square units.

Step-by-step explanation:

has coordinates and

Using the distance formula.........

Length of side

Length of side

Length of side

So, the perimeter of the triangle will be:   units.   (Rounded to the nearest unit)

The height of the triangle for the corresponding base is 8.89 units.

Formula for the Area of triangle,  

So, the area of the will be:   square units.   (Rounded to the nearest unit)
