Kylie is training for an upcoming marathon and has committed to running more than 21 miles today. If she runs from her house, she can run along two loops: a short path that is 3 miles in length, and a long path that is 6 miles in length. Select the inequality in standard form that describes this situation. (x = the number of loops on the short path, y = the number of loops on the long path).

Look at ∠A, the angle which resides on (1, 3). If we count 5 units down, you find the other endpoint on side AC. Hence, the length of side AC is 5 units. This figure is equal to the height of the graphed triangle.

If we mirror this process with the figure representing the triangle's length, side BC, we get 4 units.

The formula for calculating a triangle's area is . In this context, the base of the triangle is the same as the length. Now, let's plug in the base and the height.

The area of triangle ABC is 10 squared units.
