Answer:

6 units²

Step-by-step explanation:

The coordinates (1,1) (1,4) (5,1) form a right triangle as shown in the graph below

The base is is (1,1) and (5,1) so the length is 5-1 or 4 units

The height is (1,1) and (1,4) so the height is 4-1 or 3 units

Area of a triangle is given by

A = 1/2 bh

= 1/2 (4*3)

= 1/2 *12

= 6 units^2
