The diagonal of a rectangle is the third and longest side of a triangle with sides the same as those of the rectangle, so its length is the square root of the sum of the squares of the lengths of the sides of the triangle, (Pythoagoras' Theorem) which are also the sides of the rectangle. If the rectangle is 3 inches by 4 inches, then the diagonal is the square root of 3 squared (= 9) and 4 squared (= 16) so the diagonal is the square root of 16 + 9 = 25, giving it the length of 5 inches.
A diagonal cannot be a side of a rectangle, and a side cannot be a diagonal.
The diagonal is 25 feet.
The diagonal is 3.61cm
To find the diagonal length of a rectangle use Pythagoras' theorem for a right angle triangle.

-- A rectangle has no 'formula'. -- The length of the diagonal is 24feet 10.62inches (rounded)
Use Pythagoras' theorem to find the length of the diagonal of a rectangle.
To find the length of the diagonal in a rectangle, use the formula for calculating the hypotenuse of a right triangle: a² = b² + c². a² = 3² + 10² a² = 9 + 100 a² = 109 a = 10.44 m
If they are the dimensions of a rectangle then use Pythagoras' theorem to find the length of the diagonal.
if a rectangle has width of 5 and diagonal with lenght of 13, what is the area of the rectangle? Use Pythagoras' theorem to find the length of the rectangle which will be 12 5*12 = 60 square units
To find the length of a diagonal in a rectangle, use the Pythagorean method. Diagonal length = square root(length squared + height squared).
If by that you mean knowing only the diagonal and the width, then by the formula a2+b2=c2, where a is the length, b the width and c the diagonal. To find the width b, you need to calculate sqrt(c2-a2). For example, the width of a rectangle with length 3 and diameter 5 is sqrt(52-32)=4
A diagonal cannot be a side of a rectangle, and a side cannot be a diagonal.
The diagonal is 25 feet.
The diagonal is 3.61cm
Diagonal of a rectangle or square = square root of ( length2 + width2 )
