The answer is B! Hope this helped good luck!
Answer: 11 units
Step-by-step explanation:
Given: On a coordinate plane, the coordinates of vertices R and T for a polygon are R(−6, 2) and T(5, 2).
To find : length of Side RT of the polygon.
Using distance formula to find distance between (a,b) and (c,d):

Length of RT = 

hence, the length of RT = 11 units.
Answer:
The second side would be 15 inches.
Step-by-step explanation:
In order to determine the other side, create a proportion. On the left side, use the original dimensions. On the right side, use the new dimensions with x as the unknown.
4/6 = 10/x
Now cross multiply to solve.
10*6 = 4*x
60 = 4x
15 = x
