27' 10" = 27 and 10/12 or 27 and 5/6 or 167/5 feet
4' 6" = 4 and 6/12 or 4 and 1/2 or 9/2 feet
To get the area multiply 167/5 and 9/2 to get 1503/10 = 150 and 3/10 or 150.3 square feet
8 square feet
4 by 7 feet is 28 square feet.

It is 4 times 15 = 60 square feet
40 square feet. Multiply length by width to get square feet.
exact square footage please
The square footage is the diameter 20' divided by 2 to give a radius of 10, so r=10 pi =3.14 r=10 square footage = pi*R*R to solve 3.14*10*10= 314 square feet. It sounds like you are looking for the volume of this cylinder Volume=4*pi*r*r 1256 cubic feet or 1257.142857142856 cubic feet if you carry the constant pi out more decimal places
8 square feet
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 by 7 feet is 28 square feet.
32
You multiply them together - 20 x 4 = 80 square feet
It is 4 times 15 = 60 square feet
what is question four
40 square feet. Multiply length by width to get square feet.
13 x 4 = 52 square feet
Well, let's paint a happy little picture here. To find the square footage of a rectangle, you simply multiply the length by the width. So, for a rectangle that is 4 feet by 10 feet, you would multiply 4 by 10 to get 40 square feet. Isn't that just a lovely little calculation?
