80 sq ft
When talking about the area of a roof, remember that it is not the same as the square footage of the structure. For example a 20 x 30' building with a 12" overhang and a 4/12 pitch will have 736 sq ft of roof vs only 600 sq ft of slab. One square of shingles covers 100 square feet. 15 year shingles come 3 bundles to a square. 25 year come 4 bundles to a square.

Get your sq. footage by multiplying length times width, then find out how many tiles it takes to measure to a foot length. In this case 4 tiles = 3'. and 3 x 3 is 9 so divide 9 into your sq. footage and then you have your answer.
Area = (length) times (width) = 4-ft x 3-ft = 12 square feet(1 square foot) = (12 inches) x (12 inches) = 144 square inches12 square feet = 12 x 144 = 1,728 square inches
For square footage (area) you only have two measurements. So a carpet 4 ft x 4 ft has a square footage of 16 square feet. And a carpet of 4 ft x 8 ft has a square footage of 32 square feet. Three measurements like 4 ft x 4 ft x 8 ft give you cubic footage, or volume. So the volume of a container that size would be 128 cubic feet.
4' * 8' = 4*8 sq ft = 32 sq ft
2660 sq. ft.
12 sq ft
72 square feet (18 feet times 4 feet)
You multiply them together - 20 x 4 = 80 square feet
It is: 61*4 = 244 square feet
Assuming the room is 4 ft by 12 ft (the question does not say so), the area would be 4*12 = 48 square feet
2 ft x 4ft = 8ft²
31.65 sq'
3.5 ft * 4.5 ft = 15.75 sq feet.
If the big square is 20 ft on each side the perimeter is 4*20 = 80 ft. The small square is one-fifth of the bigger square so each side will be 20/5 = 4 ft. The small square perimeter will be 4*4 = 16 ft. Combined perimeter = 80 +16 = 96 ft.
