The distance between any 2 points P(a,b) and Q(c,d) in the coordinate plane, is given by the formula:

Thus, the distance between points (3,2) and (2,0) is:

Answer:

units
Answer:
Here
Step-by-step explanation:
length = x
width = 2x - 3
Perimeter = 2length + 2 width
2x + 2(2x - 3) = 42
2x + 4x - 6 =42
6x - 6 = 42
Add 6 to both sides
6x = 48
Divide both sides by 6
x = 8
Length = 8 inches
Width = 2(8) - 3 = 16-3 = 13 inches
