To find the measure of a singular window we need to find the area which is length times width. so that's 2.75(4) which is 11 square feet. However, Kevin has four windows which means he needs 11(4) square feet for all the windows. Which would mean Kevin needs 44 sqaure feet.
There are 54,550 more small paper clips, simply just minus 138,800 - 84,250 and that = 54,550, hope i helped!! :))
Ok ok so 28 because 9+9 is 18 and then 5+5 is 10 so you add them up and then 28
