A rectangle is removed from the right hand corner of a square board. What is the area of the remaining board in square feet?
+256 Since the board is a square the total area of the shape is 12*12 = 144. we know that the side length of the rectangle that was taken out was 10 because 2 feet of the board still remain. we know the height of the board taken out is 4, by looking at the picture, so the boards area is 144 - 40 = 104
