Divide the object into sides with lengths that are counting numbers so you can easily see this. Each counting number represents a square of area one. That means it has side length of 1. If you multiply the the length of the height and width, you are really just adding up the the unit squares.
For example, a rectangle is 7x 2 inches. The area is 14 inches. Why?
Thing of each of the 7 inches on the bottom ( could be the side too, either way)
as a unit square. Now there are seven unit squares, but since the height, or the side, is length two, we know there are two rows of unit squares. Each square has area one.
A row has area 7. Two rows has area 14. So we find the are of a 7 x2 rectangle by multiplying.

What is the formula of finding an area?
in finding the area if a square or rectangle multiply the length and width, for a triangle, multiply length and width divided by two.
Techniques in finding the area of an object?
usually, you multiply the width by the length.
What is the rule for finding the area of asquare?
Multiply the length of one side by itself !
How does finding the area of a parallelogram relate to finding the area of a rectangle?
Opposite sides are equal in length and opposite angles are equal in measure. To find the area of a parallelogram, multiply the base by the height. The formula is: A = B * H where B is the base, H is the height, and * means multiply.
What is the the formula for finding the area of a triangle?
Area of Triangle= 1/2(ab) You must multiply length b and length a together and then half it.
