which statement best describes the area of triangle abc shown below?

a triangle abc is shown on a grid. the vertex a is on ordered pair 4 and 4, vertex b is on ordered pair 7 and 2, and the vertex c is on ordered pair 1 and 2.

it is one-half the area of a square of side length 6 units.
it is twice the area of a square of side length 6 units.
it is one-half the area of a rectangle with sides 6 units × 2 units.
it is twice the area of a rectangle with sides 6 units × width 2 units.

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
