7 feet is, for all of them.
Measure both sides of the area in feet and multiply . The answer is square feet.
Area = Side * Side
Feet and square feet are two different ideas. Feet measure length, sq. feet measure area. A 'square foot' denotes an area equal to that of a square with sides equal to 1 foot in length. This area, though, need not be square-shaped. It just needs to have a total area that is the same as the above mentioned square.
Measure its side in terms of feet. Multiply that measure by itself to give the area in square feet.
To convert square feet to feet, you need to take the square root of the given area. In this case, the square root of 10000 square feet is 100 feet. This means that a square with an area of 10000 square feet would have sides that are each 100 feet long.
Just remember that the square of the hippopotamus is the sum of the square of its two sides.
You don't measure the length and width in square feet. Square feet is an area. You measure the length and width in feet, then multiply them to get the area in square feet.
If a square's area is 10 square feet, the length of one of its sides is 3.16227766 feet.
4 square feet.
The area of a square cannot be 196 feet. If the area is 196 square feet (which is an entirely different thing) its sides are sqrt(196) = 14 feet.
A square with a side length of 63 feet has an area of 3,969 square feet.
10 square feet is a measure of an area. The area can, of course, be of any shape - simple or complicated. Two simple shapes, each with an area of 10 sq feet area circle with a diameter of 3.57 feet (approx) ora square with sides of 3.16 feet (approx).
