To find the length of side BC of polygon ABCD, you can use the distance formula or simply find the difference in the x-coordinates since both points have the same y-coordinate (5).
The coordinates for side BC are:
The length of side BC can be calculated as follows:
Length = x2 - x1 = 5 - 2 = 3 units.
Therefore, the answer is:
A. 3 units
Yes, I am sure that the calculation is correct.
To recap, the coordinates for points B and C are:
Since both points lie on the same horizontal line (both have the same y-coordinate of 5), the length of side BC can be calculated by finding the difference between the x-coordinates:
\[ \text{Length of BC} = x_2 - x_1 = 5 - 2 = 3 \text{ units} \]
Thus, the length of side BC is indeed 3 units, which corresponds to option A.
