Best ResponseYou've already chosen the best response.0The area of a rectangle is just \(\huge l*w\). If \(l=9.00\) and \(w=4.25\), then the area of the rectangle is \(\huge 9.00*4.25=?\).

Best ResponseYou've already chosen the best response.0\(\huge 38.25\) has four significant digits. You want three, so you will round it to the nearest tenths.
