It depends on what the shape is. There are relatively simple formulae for triangles, circles, parallelograms, regular polygons; and more complicated formulae for ellipses, irregular polygons and other shapes.
If the shape can be described algebraically, then integration may provide an answer.
Then there are non-analytical methods for very irregular shapes. You can get an estimate by mapping the shape onto a grid and counting the number of squares covered and part covered. Or you can cut out an identical shape from a uniform lamina and compare its mass to the mass per unit area.

Can a non rectangular parallelogram and a rectangle have the same area?
Yes.
Do you times area of a rectangle?
The area of a rectangle is found by multiplying the length times the width.
What is the area of of a rectangle 4m x 3.5m?
The area of a rectangle is found by multiplying its length by its width, so the area of a rectangle that measures 4m x 3.5m is 14 square meters.
How to get the deminsions of a rectangle?
The dimensions of a rectangle are the length and the width. With these two measurements , the area of the rectangle can be calculated : Area = length x width. The perimeter can also be found : Perimeter = (2 x length) + (2 x width).
What is the area of a rectangle 5x7?
The area of rectangle is : 35.0
