To do that you have to find the length and width and then multiply them to get the areaFor example a square has 3 ft length and 4 ft width. H vertical height. To find amount of rectangles that fill area of room you multiply denominators.
To do this - follow the steps in.
Area 9 mm x 4 mm 36 mm 2 Area 7 cm x 6 cm 42 cm 2 Area 8 m x 2 m 16 m 2. To find amount of rectangles that fill area of room you multiply denominators. Unit for measurement of the area is in square terms. The width is 5 and the height is 3 so we know w 5 and h 3.
