Area of rectangle

Answer 1

Can you draw a diagram?

Remember these fundamentals:

The distance between two points \((x_1,y_1)\) and \((x_2,y_2)\) is \(\sqrt{(y_2 - y_1)^2 + (x_2 - x_1)^2}\). Two opposite sides are parallel and have the same slope. Two adjacent lines are perpendicular so the slope of one line is the negative-reciprocal of the other.

Answer 2

ohh, am so sorry for you, when did all this happen? :(
