If the base of a rectangle is 18m, and the side is 20 m, then the area cannot be 108m. (It cannot be any number of metres since area must be measured in square metres, but that is another matter)

Divide the area by the height
If you draw a diagonal in a rectangle you get two equal triangles, each half the area of the rectangle. Area of rectangle is base x height, so half of that is ½ x base x height. QED
A rectangle is a good, simple shape to begin with. The area of a rectangle is equal to the product of the length of its base and the length of its height. The height is a segment that is perpendicular to the base. For a rectangle, the base and height are often called the "length" and the "width", and sometimes the height is referred to as the "altitude."
The area of rectangle is : 120.0

7. Since the area of a rectangle is base x height, the base must be the area (28) divided by the height (4). 28/4 = 7
The area of rectangle is : 20.0
Area of rectangle = Base x Height = 2.25 x 3.2 = 7.2 sq. units
Sounds like the triangle is spread out so that (the point is at the top of the rectangle) and (the base of the triangle is the same as the base of the rectangle).Base of rectangle = base of triangleHeight of rectangle = height of triangleWrite the formulas:Area of the rectangle = (base) times (height)Area of triangle = (one half of) (base) times (height)Can you see the ratio now ?
find the area of a rectangle with base 4 ft and height 4 in?
Area = (base) x (height)= (5y - 3) x (11)= 55y - 33
