    Question Programs or site that will plot this?

    I need to plot a few coordinates of a rectangle in order to find the area. The coordinates are (-52, 73), (96, 73), (96, 1483) ... and I am expected to find and plot the 4th coordinate in order to form a rectangle. My question is is there a website that will plot these coordinates and give me the area (or make it easy for me to find the area)??? Because it would be really unhandy to graph this by hand. Or is there a simple way to find the 4th coordinate and area?

    You're give the bottom line of the rectangle. Then, with the point (96, 1483), you know the final point completing the rectangle has to be at (-52, 1483). Do you see why?

    1483 - 73 = 1410

    This is one side of the rectangle (length)

    96 + 52 = 148

    This is another side of the rectangle (width).

    Now that you're given the length and width, can you find the area? ( A = l\cdot w)

    Another approach would be to find the area of the triangle formed by these 3 points and multiply it by 2. Both ways are just as easy.

    Woah I didn't know you could find that mathematically! You are super cool!
