You don't - you need additional information. Many different rectangles can have the same diagonal. If you know the diagonal and one side (which must be LESS than the diagonal), you can use Pythagoras' Theorem to calculate the other side.
A rectangle can have only 2 dimensions and so finding the area from the given 4 dimensions has many possibilities.
The height and longer diagonal do not provide enough information to calculate the sides.
You CAN'T calculate the surface area of a rectangle, given only its perimeter. The answer varies, depending on the length-to-width ratio of the rectangle. Thus, you would need some additional information; for example one of the following:* The length * The width * The length-to-width ratio * The length of the diagonal * Some other data that will let you calculate the remaining information about the rectangle.
To determine the perimeter of a rectangle, we need both the length and width. The area of the rectangle is given as 20 cm², but without the specific dimensions, we cannot calculate the perimeter directly. For example, if the rectangle has a length of 5 cm and a width of 4 cm, the perimeter would be 2(5 + 4) = 18 cm. Thus, the perimeter varies depending on the rectangle's dimensions.
Divide the rectangle in two triangles and then use the pythagorean theorem to find the remaining sides.
The dimensions given appear to describe a rectangular box, with 3 separate pairs of rectangles: 4X8 -> Diagonal is 8.944 ft 4X12 -> Diagonal is 12.649 ft 8X12 -> Diagonal is 14.422 ft
That depends on the given dimensions which are not in the question.
The diameter of a rectangle is the same as its diagonal (angle in a semicircle is a right angle). So the diagonal forms a right angled triangle with the diagonal as the hypotenuse and two sides of the rectangle (a length and a breadth) forming the legs of the triangle. If the lengths of the sides of the rectangle are known, a simple application of Pythagoras's theorem given the measure of the diagonal.

The height and longer diagonal do not provide enough information to calculate the sides.
We can't calculate anything regarding the rectangle, as there's a strong indication that there must be something fishy about it. A rectangle has only two dimensions, and we can't imagine what to do with the three numbers given for the rectangle in the question.

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).
The dimensions of a rectangle, usually, refer to the length of the external sides. Calculation is not necessary in most cases, measurement is. Calculation is necessary when for instance you are given a set of dimensions and asked a question related to that information examples are; What is the area of a rectangle that is 4 x 4 units What is the length of the other side of a rectangle if one side is 2 and the area is 12
