Area of a rectangle is length x width. It isn't clear what the width is in this case - or how you could solve for it.
To solve for the inverse of an equation, first, replace the function notation (e.g., (y = f(x))) with (y). Then, swap the roles of (x) and (y) in the equation. After that, solve for (y) in terms of (x). Finally, replace (y) with (f^{-1}(x)) to express the inverse function.
You take the formula for a rectangle, replace what you know, and solve for the remaining variable.
Decimals are simply a way to express numbers. There is nothing to solve!

Add together the lengths of each of its sides.

In a rectangle: P = 2(L + W) and A = LW P = 2(L + W) (replace P with 20) 20 = 2(L + W) (solve for L; divide by 2 to both sides) 10 = L + W (subtract W to both sides ) 10 - W = L A = LW (substitute 10 - W for L) A = (10 - W)W A = 10W - W2
There is no "height" of a rectangle, unless it's a rectangular prism. Do you mean the length? If you have the area of the rectangle, the equation should be:A= L x WPlug in the area and the length and solve for the width, or plug in the area the width of the rectangle, and solve for the length.
It really depends on the specific function, and what you want to solve for.

You can certainly express the radius as a function of its area, yes. If the area is known, you can solve the formula for the area of the circle to uniquely get the radius. (The quadratic equation has two solutions; you will of course choose the positive solution for the radius.)
Add together the lengths of each of its sides.
For a rectangle, it is 2(l + w) l = length w = width
Write an equation for the perimeter, and solve it. Remember that the perimeter is the sum of all four sides.
Make sure you know the length and width of the rectangle in the SAME UNITS ... both in inches, or both in meters etc. Then just multiply the two numbers ... Length x Width. The answer is the area of the rectangle.
