Using Equations to find Area
You can use equations to find the area of shapes:
Area of a rectangle is A=bh
Area of a triangle is A=bh
2
Area of a circle is A= 3.14r2
(A=area, b=base, h=height)
To find the area of a rectangle:

Just plug the numbers in where the variables are and solve.
What if you know the area and one side, but not the other?
Area = 27
