Question

what is the perimeter of square ghij? write your answer as an integer or as a decimal rounded to the nearest tenth. perimeter = units

Explanation:

Step1: Find side length of square

Points G(-6, 0) and H(-9, 0) (wait, no, looking at the grid: G is at (-6, 0), H is at (-9, 0)? Wait, no, the horizontal distance between G and H: G is at x=-6, H is at x=-9? Wait, no, the grid: each square is 1 unit. Wait, G is at (-6, 0), H is at (-9, 0)? Wait, no, the horizontal line: G is at (-6, 0), H is at (-9, 0)? Wait, no, the distance between G(-6, 0) and H(-9, 0) is |-6 - (-9)| = 3? Wait, no, wait the vertical line: G(-6, 0) and J(-6, -3)? Wait, no, J is at (-6, -3)? Wait, I is at (-9, -3), J is at (-6, -3). So the length of GJ: from y=0 to y=-3, so vertical distance is |0 - (-3)| = 3. Or horizontal distance between G(-6,0) and H(-9,0): |-6 - (-9)| = 3. So side length of square is 3.

Step2: Calculate perimeter of square

Perimeter of square = 4 side length. So 4 3 = 12.

Answer:

12
