This is how the human body surface area was calculated as well: subject's bodies were covered in stripes of paraffin, which were then removed, sliced and measured. triangle base height Triangle Area × b × h b base h vertical height Square Area a a length of side Rectangle Area w × h w width h height. Irregularly shaped areas are often divided into several rectangles when one needs to calculate their area, but can't do a precise calculation. The area of a rectangle depends on its sides.
Practical applicationsĪrea of a rectangle calculations have a vast array of practical applications: construction, landscaping, internal decoration, architecture, engineering, physics, and so on and so forth. The formula for calculating the area of a rectangle is ABase×Height. Since in multiplication the order in which the numbers are multiplied does not matter, you need not worry about switching the places of the two measurements. If we know two sides of the rectangle that are different lengths, then we have both the. A rectangular bedroom with one wall being 15 feet long and the other being 12 feet long is simply 12 x 15 = 180 square feet. To find the area of a rectangle, multiply its width by its height. For example, a garden shaped as a rectangle with a length of 10 yards and width of 3 yards has an area of 10 x 3 = 30 square yards. Students may struggle when all four side lengths are given. If 25 cm is the length of the sheet, find its width.The area of any rectangular place is or surface is its length multiplied by its width. Students will then work on two problems where they will use the formula for a rectangle and a square. Suppose you are repainting the walls of your bedroom. This next example is an extremely common, practical use for finding area of rectangles. Q: The area of a rectangular sheet is 500 cm². The floor and carpet area is: a r e a 4 m × 3 m. So, cost of painting the total area of the rectangular land = 0.50 x 150000 = Rs 75000. Now, let us calculate the cost of painting the land.Ĭost of painting of an area of 1 square meter = Re 0.50 Thus, Area of the rectangle A = 500 m x 300 m = 1, 50,000 square meters. ('Area of Triangle is: ' + area) Output displayed here. Also, find the cost of painting the sheet, if a painting of an area of one square meter costs 50 paise.Īns: The Area of a rectangle (A) = l x b, where l is the length and b are the breadths of the rectangle. double arealb The formula to find out the area of the rectangle. Q: The length and the breadth of a rectangular piece of land are 500 m and 300 m respectively find its area. Now that we have some clarity about the concept and meaning of area of rectangle, let us try some examples to deepen our understanding of the subject. Let us now take a deep look into the formula. The unit of area of the rectangle is square units. The area of a rectangle is the product of its two sides, multiplying the length and its breadth. Here, in the case of a rectangle, its length and breadth are not equal. Because of this property, we say that the two diagonals of a rectangle are congruent.Īn object in two-dimensional geometry must have measured for length and breadth. Diagonal is a line that is drawn inside the rectangle connecting the opposite corners or vertices.
Another property of a rectangle is that has two diagonals of equal length. It is an equiangular rectangle with four right angles which is 90 degrees. Since a rectangle has four sides, it has four angles. The opposite sides of a rectangle are parallel and of equal length. A rectangle is a quadrilateral with four sides. Let us first understand the shape and structure of a rectangle. Want to know why this formula works Check out this. 2 Solved Examples Area of Rectangle Formula To find the area of a rectangle, we multiply the length of the rectangle by the width of the rectangle.
