It depends on the symmetry. Work out the area of half the shape by filling the shape with squares and triangles of known areas and times the answer by two.
To work out the area of a composite shape, you will have to divide it into smaller figures.
The perimeter has nothing to do with the area you have to times the width times height times length and that will give you the area of the shape
A regular shape such as a square or rectangle - length times width. If it is an irregular shape, fit known sized squares and triangles within the shape's border and work out area of a square and a triangle times the number of squares and triangles.
you times the width by the legnth of the shape
You times the length by width, to get the area of the 2D shape.
you times the width by the legnth of the shape
you times the width by the length of the shape
The area of a sphere is equal to its circumference times its diameter.There are a variety of ways to work out this formula, most of them involving calculus.(See the links for the volume of a sphere).
you times the width by the legnth of the shape and then add them together
The area of any rectangular shape, including the square, is the length times the breadth. Area = length x breadth
length times width
