Question

On a coordinate plane, the points (3, 4), (8, 4), (5, 0), and (0, 0)

form a parallelogram. What is the perimeter of the
parallelogram?

Answer 1

18

Explanation:

1. Find the distance between (3,4) and (8,4)

- Subtract the x coordinates to find the distance (we subtract the x coordinates because it is horizontal)

- The distance between these points should be 5

2. Find the distance between (8,4) and (5,0)

- Subtract the y coordinates to find the distance (we subtract the y coordinates because it is vertical

- The distance between these points should be 4

3. Multiply each difference (5 and 4) by 2

- We multiply because the two sides have the same length and width ( which is 5 and 4)

- When we multiply, we should get 10 and 8

4. Add the products (10 and 8) together to find the perimeter

- The final answer should be p (perimeter) = 18
