So make certain you can identify the two linear measurements of the rectangle. The perimeter of the rectangle is the sum of all its four sides. The formula to calculate the area of a rectangle is given as Area w h For example if a rectangle is 8 m wide and 3 m high The area of the rectangle is Area w h.
Area length width a r e a l e n g t h w i d t h If you do not know what the length of a rectangle is though that formula will not do you much good.
The formula for the area of a rectangle is width x height as seen in the figure below. Parallelogram Area b h b base h vertical height. Now let us calculate the cost of painting the land. Rectangle Area w h w width h height.
