Question

10 POINTS!!!! Please help

Answer 1

Answer:

10 units²

Step-by-step explanation:

The length of side AB is 3 -(-1) = 4 units long. This is the base of the triangle.

The distance from vertex C to the line x=3 is 3-(-2) = 5 units. This is the altitude of the triangle.

The area is half the product of altutude and base length.

... A = (1/2)bh = (1/2)(4)(5) = 10 . . . units²
