20 by 2 = 40
40 by 10 feet = 400 feet.
twenty . 10 - 8 = 2 2 / 10 = 20 / 100 = 20%
= 20 sq feet
There are 10 fathoms in 20 feet. One fathom is equal to 6 feet, so 20 feet divided by 2 equals 10 fathoms.
perimeter of a rectangle = 2 *(l+ b) = 2*(10)=20 feet
The area of 20 feet times 10 feet = 200 square feet.
The theoretical mechanical advantage is the length of the ramp divided by its height. 20/2=10.
Square feet is the product of lenght times width. Any 2 numbers that = 20 when multiplied. 1 x 20 = 20; 2 x 10 = 20; 4 x 5 = 20
The wave base (the depth at which water moves) would be about 10 feet, or 1/2 the wavelength.
2 faces each 2' x 10' = 20 square ft2 faces each 2' x 3' = 6 square feet2 faces each 10' x 3' = 30 square feetTotal = 2 x (20 + 6 + 30) = 2 x 56 = 112 square feet
Diameter = 20 inch => radius = 10 inches = 10/12 feet. So area = pi*(10/12)^2 = 2.1817 sq feet approx.
20' x 10' (200 square feet) = 22.22 square yards.
To compare 20 feet and 10 yards, we need to convert one of the measurements to match the other. Since 1 yard is equal to 3 feet, 10 yards would be equal to 30 feet. Therefore, 10 yards is greater than 20 feet.
