I don't see how this is math related but let me ask why do you want to? Best friends don't normally leave when things get tough. I mean I do understand. And I will tell you my opinion if you truly want it as well. Jw.
To find the area of a rectangle, do length times width. Because we know the length (90 in), we can divide 380 by 90 to find the maximum possible width. This is possible because of the equation width = Area/length, which is derived from width * length = Area. 380/90 = 4.222, so the maximum width to the nearest possible inch is 4 inches.
The answer is 1.80 because
0.25 times 3.00 is 0.75
minus 0.75 to 3.00 and it will be 2.25
0.20 times 2.25 will be 0.45
minus 0.45 to 2.25
and u will get 1.80
