An unknown quadrilateral has these points: A (0, -3), B (6, -3), C (9,1), D (3,1)
What is the length of side BC? (hint: use the distance to find how far apart point B is from C)
BC = 7
BC = 5
BC = 4
BC = 6
choose the correct answer
To find the length of side BC, we can use the distance formula:
Distance = √((x₂ - x₁)² + (y₂ - y₁)²)
In this case, the coordinates of point B are (6, -3) and the coordinates of point C are (9, 1).
Using the distance formula, we can calculate the length of side BC:
BC = √((9 - 6)² + (1 - (-3))²)
= √((3)² + (4)²)
= √(9 + 16)
= √25
= 5
Therefore, the length of side BC is 5.
So, the correct answer is BC = 5.
