You can't.
Suppose for instance your rectangle is 1xA, then the diagonal length is sqrt(1+A**2). But if your rectangle is sqrt(A)xsqrt(A) then your diagonal length is sqrt(2*A).
The only thing one can say for sure is that the diagonal length is at least sqrt(2*A).

Area rectangle = length x width (using same units).
The area of a rectangle is length times width. If you have the length and a diagonal, you will first have to figure out the width, using the formula of Pythagoras. length2 + width2 = diagonal2; solving for width: width = square root of (diagonal2 - length2). Once you have the width, just multiply lenght x width.
We can use either meter or centimeter to measure a rectangle. For a large area of rectangle we can also use "feet" or " yards". Using "meter" is a convenient form to measure the length of the rectangle.
By splitting the rectangle into half diagonally, we obtain two right triangles with sides 40 and 60. Using Pythagorean theorem, we obtain approximately 72.11 as the hypotenuse of both of them.
The formula for the area of a rectangle is length x breadth. In order to prove this works, work out an area of a rectangle using that formula.
Using Pythagoras' theorem its width is 6 units in length.
To find the length of a side, you either measure it, or you calculate it. How you calculate it depends on what data is given. For example, if you have the coordinates of the endpoints of a line, you can calculate the length by using the Pythagorean theorem (or simply subtracting the coordinates of the two endpoints, if the line is perfectly vertical or perfectly horizontal).
25cm - without using a calculator !
By using area of a rectangle do you remember in 7th grade when you had to do this:Area of RectangleA=LxWlenght x width
You cannot since a rectangle is a two-dimensional figure. It has no depth, no volume, no mass.
If the shape is a rectangle (or square), then Perimeter = 2*(Length + Breadth) So Breadth = Perimeter/2 - Length
