Question

The coordinates of the vertices of the triangle are

Answer 1

Answer:

The height of the triangle PQR is given by:

h = 4 + 8

h = 12 units

Now, the area of the triangle PQR is:

= 108 square units.

Step-by-step explanation:

Answer 2

The area of the triangle PQR is 108 square units

How to determine the area of the triangle?

The given parameters are:

• Height, h =  12 units
• Base, b = 18 units

The area is then calculated using:

Area = 0.5 * base * height

So, we have:

Area = 0.5 * 18 * 12

Evaluate

Area = 108

Hence, the area of the triangle PQR is 108 square units
