The formula for the area of a rectangle is length x breadth. In order to prove this works, work out an area of a rectangle using that formula.
length*breadth
A = LW divide by W to both sides A/W = L
a rectangle has four right angles and opposite sides are all the same length This means that a parallelogram is not always a rectangle, but a rectangle is always a parallelogram, by definition.
the area of a rectangle = length x widthwe can rearrange this to give uslength of a rectangle = area/ width
formula for area of a rectangle is length times width in this equation 15ft is your length and 10ft is your width so.... 15 x 10 = 150 your final answer is 150ft squared (150 feet squared)
The area formula for the parallelogram is related to the area formula for a rectangle because you can make the parallelogram into a rectangle to find the area.
The formula for the area rectangle
If the base is a rectangle, use the formula for the area of a rectangle.
Area of a rectangle: a = l * w
The formula is for a square and rectangle is A=bh or A=lw
Use squares and try it out for yourself. Get a number of squares and make a rectangle 3 squares long by 4 squares wide. Count the squares. You should have 12 squares (or 3*4). That's the best way I know to prove the formula.
A = lw Area of a rectangle = length times width
In the formula for the rectangle, put the width equal to the length.
The area of a rectangle is length times width.

That depends what kind of figure you are talking about. The formula for the area of a circle is quite different from the area of a rectangle, for example.That depends what kind of figure you are talking about.
