Ricky's computer monitor is a rectangle. the length is 15 inches and the with is 12 inches. estimate the area of the monitor

Well, area is length times width. So, we are multiplying 20 times 10, because 15 is closer to 20 and 12 is closer to 10. Therefore, 2 times 1 is 2, add two zeroes to the end and you get 200 inches!

For the exact answer it is 180 which is still technically estimated
