The width of a rectangle is shown below:
A coordinate plane with a point A at negative 3, 3 and C at negative 3, negative 2.
If the area of the rectangle to be drawn is 20 square units, where should points B and D be located if they lie to the right of points A and C?
B(1, 3) and D(1, −2)
B(3, 3) and D(3, −2)
B(2, 3) and D(2, −2)
B(1, 2) and D(1, −3)

-3? @nelsonjedi

Distance formula between two points is\[d= \sqrt{(x2-x1)^{2}+(y2-y1)^{2}}\]

...huh? @nelsonjedi
OpenStudy (anonymous):
You have two points (-3,3) and (-3,-2) we will call them (x1,y1) and (x2,y2)...so to find the distance between these two pints we plug them in the equation above and get \[d=\sqrt{(-3-(-3))^{2}+(-3-(-2)^{2}}\]
OpenStudy (anonymous):
Which becomes \[d=\sqrt{0^{2}+(-5)^{2}}....or .....\sqrt{25}....which.. equals..what..?\]
