If P = 40 then L + W = 20. The only combination which gives A = 100 is where L and W are both 10, ie the figure is a square of side 10 cm.

What is perimeter of square with area of 100meters squared?

Area of a square = (side length)2 = 100 meters2Side length = sqrt( 100 meters2 ) = 10 metersPerimeter of a square = (4 x side length) = 4 x 10 = 40 meters


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


What is the perimeter of a square that has an area of 100 m?

The perimeter is 40m


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.

What is the perimeter of a square with an area of 100?

It is: 4*10 = 40 units of measurements The area for a square is length squared. so if we have L2=100, then square root of 100 is length which is 10. The perimeter of a square is the distance around the square, and if we add 4 lengths (because all lengths in a square are the same), we get 10x4 which is 40.


How is the perimeter and area of a square related?

There is no direct relationship. The perimeter is proportional to the length of the side (if you increase the side by a factor of 10, the perimeter will also increase by a factor of 10); the area is proportional to the square of the side length (if you increase the length of a side by a factor of 10, the area will increase by a factor of 100).If you know the perimeter, divide it by 4 and then square the result, to get the area (A = (P/4)2); if you know the area, take the square root and then multiply by 4 to get the perimeter (P = root(A) x 4).There is no direct relationship.

The perimeter of a square is 100 feet and the area is 625 square feet What is the length of each side?

Perimeter is 100', so each side = 25' and 25 squared = 625. QED
