To find the area of an arrow you can first divide it into two shapes, a rectangle and triangle. First find the area of the rectangle then the area of the triangle. Then when you find both areas of the two shapes add them up to get the area of the arrow. If you don't know how to find the area of those two shapes you are so far lost.

1 method is to multiply length times the width and the 2 method is to divide the rectangle into triangles and find the area of one of the triangles and multiply the area by two.

The area is the inside. The perimiter is around. If its a rectangle, to find the area you multiply the lengths of two sides

They are both made of 4 sides and someone told me this but anyways, they have the same perimeter/area

To find the area of an arrow you can first divide it into two shapes, a rectangle and triangle. First find the area of the rectangle then the area of the triangle.

1.) You can measure the sides of the shapes and add

Divide the rectangle in two triangles and then use the pythagorean theorem to find the remaining sides.

If the length and the breadth of the rectangle represent the two numbers, then the area of the rectangle is equal to their product. But, how do find the area? You multiply the two numbers. So this appears to be a long way to do something that is inherently straightforward!

There are many ways to find the area of an odd shape. Usually, you have to break the shape down into shapes that you can calculate the area of, and then add the areas of all of those individual shapes to get the area of the entire odd shape.Example:_____|_____\There is no way to find the area of this figure, so you have to break it down into two, easy to find shapes.____|___|\You can see that there is a rectangle and a triangle. You can easily find the area of a rectangle with L X W, and a triangle with 1/2(b)(h). Since it is impossible to find the area of that irregular quadrilateral in one equation, you have to split it into two known shapes (the rectangle and triangle), find the area of each, and then add the areas together to get the area of the entire piece.

You can find the perimeter of a rectangle if you know its area and the length of one side. Divide the area by the length of the known side and the quotient will be the length of a side perpendicular to the known side, and then multiply the sum of the two sides by two to find the perimeter.

Suppose you are asked to find the area of a rectangle that is 2.1- wide by 5.6- long. Your calculator answer would be 11.76 . Now suppose you are asked to enter the answer to two significant figures.
