Question

graph rectangle fghi with vertices f(6, 2), g(-1, 2), h(-1, 10), and i(6, 10).
what is the perimeter of rectangle fghi?
perimeter = \boxed{} units

Explanation:

Step1: Find length of FG

Points F(6,2) and G(-1,2) have same y-coordinate. Length is $|6 - (-1)| = 7$.

Step2: Find length of GH

Points G(-1,2) and H(-1,10) have same x-coordinate. Length is $|10 - 2| = 8$.

Step3: Calculate perimeter of rectangle

Perimeter formula: $P = 2\times (length + width)$. So $P = 2\times(7 + 8) = 2\times15 = 30$.

Answer:

30
