Can someone please explain this to me. The four vertices of a rectangle drawn on a complex plane are defined by 1 + 4i, 2 + 4i, 2 – 3i, and 1 – 3i. What is the area?

Best ResponseYou've already chosen the best response.0The complex numbers you're given are essentially the coordinates (1, 4), (2, 4), (2, 3), and (1, 3) on a grid. So you'd have this: dw:1434027220500:dw
