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).

To find the area of a rectangle, you need to know the formula: Area = length x width. Given that the perimeter is 72m and the width is 16m, we can calculate the length by using the formula for perimeter of a rectangle: Perimeter = 2(length + width). Substituting the values we have, 72 = 2(length + 16), which simplifies to length + 16 = 36. Therefore, the length of the rectangle is 20m. Finally, the area of the rectangle is 20m x 16m = 320 square meters.
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.
To find the width of the rectangle using synthetic division, we need to express the area, given as ( A = x^2 + 3x ), in terms of the length and width. If we assume the length is ( x + 3 ), we can set up the equation ( A = (x + 3) \cdot \text{width} ). Dividing ( x^2 + 3x ) by ( x + 3 ) using synthetic division will yield the width. The result of this division shows that the width is ( x ).
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).
Well, isn't that just a happy little problem to solve! To find the area of a rectangle, you multiply the length by the breadth. And to find the length, you can use the formula: length = (perimeter - 2 * breadth) / 2. Just remember, there are no mistakes, only happy accidents in math!
