Step-by-step explanation:
Let

we know that
The perimeter of triangle is equal to

the formula to calculate the distance between two points is equal to
step 1
Find the distance AB

substitute in the formula
step 2
Find the distance BC

substitute in the formula
step 3
Find the distance AC

substitute in the formula
step 4
Find the perimeter

substitute the values

-6 and 2/3 is the correct answer.
The area would be .4 cubic feet. The perimeter would be 2.1
The relationship here between the x and y values can be seen in an equation, y=x+3, since every y value is three more than its corresponding x-value. <span />
