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 a rectangle is length x width. The area of a triangle is 1/2 base x height. If you mean a rectangle, the area is 70 square units. If you mean a triangle, the area is 35 square units.
Area of a parallelogram = 0.5*base*height = 0.5*6*3 = 9 square inches.
The base area cannot be 56 inches because 56 inches is NOT a measure of area - it is a measure of distance.If, the base area was 56 SQUARE inches, the area would be 56*6 = 336 CUBIC inches.
