### How big is a square that is 100 square inches?

A square has 4 sides that are of equal length. The area of a
square is the length of one side multiplied by itself, or squared.
So, to find the length from the area you must take the square root
of the area, or in other words find that number that when
multiplied by itself gives the area.
square root (100) = 10
This is because 10 x 10 = 100
So, each side of the square is 10 inches.

### The perimeter of a square is 100 feet and the area is 625 square feet what is the lenght?

On a square all 4 sides are the same length. If the perimeter is
100 that means all 4 sides add up to 100. That means you can divide
100 by 4 and get the length of any one side. The area is 625. You
can then take the square root of 625 and also get the length of any
one side. Guess what? Both numbers are the same. The square root of
625 equals 100 divided by 4. Either way you get the length of any
one side of the square, which is 25.

### How do you find area of square if diagonal is given?

Using Pythagoras' theorem which says that the square on the
hypotenuse (in this case the diagonal) is equal to the sum of the
squares on the other two sides (which in the case of a square would
be equal in length).
so if the diagonal measured 10 units, the square on the diagonal
would be 100 square units. And as this = 2*the squares on the other
sides, the square on one side would be 100/2 = 50 square units.
As a square has sides of equal length the square on one side is
actually the area of the square.
i.e. the area of a square with a diagonal of 10 units is 50
square units.
or generically the area of a square with a diagonal of length
'x' = (x2)/2

### How do you find the area of a square if given a perimeter?

The perimeter of a square is the measurement of all the external
sides, of which there are of course 4.
We also know that for a square all of these 4 sides are of equal
length.
Therefore if we divide the perimeter by 4 we get the length of
one side.
If you then square this length (multiply it by itself) you get
the area of the square.
so if the perimeter measurements was 40 units
40/4 gives you the length of one side = 10 units
and 10*10 gives you the area of the square - 100 square
units.
thus generically the area of a square with a perimeter of 'x' =
(x/4)2

### How many inches is 100 square inches?

Invalid conversion: square inches is a measure of area
and inches is a measure of length or distance.
If each side of a square is 10 inches long, the area of the
square will be 100 square inches. (10*10=100)
For any rectangle with an area of 100 square inches, the length
of the short side times the length of the long side must total
100.
(For instance, a rectangle 4 inches by 25 inches: 4*25=100)
