<PRE><B>Question 830685</B>
You can do this two ways.  Find the area in cms and then convert to sq ft.  Or convert to sq ft first.  Easier for me to find the cm area first.
.
Area = L * W
350 * 135 = 47,250 square cm
There are 929.0304 square cm in a square foot.
Divide 47,250 by 929.0304 to get 50.8594767189075 square feet.
.
To do it the other way, convert the cm first.
350cm = 11.482939632535 feet
135cm = 4.4291338582635005 feet
Multiply to get the area
