John was visiting four cities that form a rectangle on a coordinate grid at A(0,4), B(4,2), C(1,-4) and D(-3,-2). What is the area of the space that cities enclose? Round your answer to the nearest whole number. Do not include units in your answer.

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212
