Best Answer

It depends on the shape, whether it gives you the dimensions or not, or whether you can divide it up into separate shapes.

You need to break down the composite figure into simpler shapes whose areas you can calculate using appropriate formule and then add together the areas of all the individual bits.

You cut the shape down into smaller shapes that you recognise and know how to calculate the area of. Then calculate the area of the small shapes and add the all up.

Calculate the area of the shape. The formula to be used will be different for different shapes.

It depends on the shape whose area you wish to calculate. Different shapes have different formulae.

You measure or calculate the area. How you do that will depend on the shapes involved.

They are the result of combining shapes, either by adding parts or taking parts away. We calculate the perimeter of composite shapes by splitting them into simpler pieces and then calculating the perimeter of those simpler pieces.

Break it down into smaller shapes, find the area of those bits, then add them all together.

There are different formulae for different shapes and these vary in complexity.

Cut them into triangles and use the pythagorean theorem

To find the area, first divide the shape into regular, simple shapes. Then use formulas to find the area of the smaller, regular shapes. Lastly, add up all the smaller areas to find the area of the original shape.

To find the volume of a composite figure, you would need to break it down into simpler shapes (such as cubes, prisms, cylinders, etc.), calculate the volume of each individual shape using its respective formula, and then add or subtract the volumes of the individual shapes to find the total volume of the composite figure.

You do not. As two-dimensional shapes geometric squares have area and no volume whatsoever.
