Question

A quadrilateral is drawn on a coordinate plane with the points A (-4,8) , B (6,8), C (6,4), and D(-4,4). What is the length, in units, of side AB?

Answer 1

The length of side AB is 10 units.

Step-by-step explanation:

To find the length of side AB, we can use the distance formula, which states that the distance between two points (x1, y1) and (x2, y2) is given by the formula:

d = √((x2 - x1)² + (y2 - y1)²)

In this case, the coordinates of points A and B are (-4, 8) and (6, 8) respectively.

Plugging in these values into the distance formula, we get: d = √((6 - (-4))² + (8 - 8)²)

d = √(10² + 0²) = √(100 + 0) = √100 = 10
