diagonal = square root ( side squared + side squared) = square root (2) x side
(pythagorean theorem since angle is 90degrees)
Area in square units = pi*radius2
a square + b square = c square this is the formula for Pythagoras in maths. it is to find the hypotenuse of a right-angled triangle
When you think about it for a while, they're really NOT different. The rectangle formula needs a bit more detail, because its sides don't all have the same length, so its length and its width have to be handled separately. But the rectangle formula works perfectly well if you use it to find the perimeter of a square.
In UK terms:- Area = 0.5*(sum of parallel sides)*height and measured in square units
lengthXwidth
perimeter = 4 x sqrt 72 = 33.94 in area = 72 squinches
13.2077 cm (12x12) + (12x12)= 288 square root of 288 = 13.2077...
rectangle a set that goes horizontal and a set that goes diagnal
each side = sqrt (1600/2) ie 28.28 cm
The length of the diagonal of a square with sides 5 is 5√2. This is because of the properties of a 45-45-90 triangle.
Square is a special case of a rectangle and the same formula may be used to find the perimeter

The formula for the area of a square is A=s2. So to find the sidelength, find the square root of the area.
Area in square feet = pi*radius2
let x be the sidelength of the squareby pythagoras' theorum:x2+x2 = 1222x2 = 144x2 = 72x = 6*(2)^0.5 [2^0.5 is the square root of 2]x = 8.4852813742385702928 (20sf)perimeter = 4xperimeter = 33.941125496954281171(20sf)
What is a square m3? If it is a measure of hyper-volume in 6-dimensional space, then presumably the formula is analogous to the formula for volumes in 3d space.
To find the surface area of a square, multiply the length of the square times the width.
