The kennel floor measures 54 inches long and 36 inches wide. Suppose you need a soft blanket for your dog's daytime kennel. A typical gallon of paint covers 400 square feet, so you will need one gallon of paint. Be sure to include the units of the measurements in your answer. For example, a rectangle with a base of 6 and a height of 9 has an area of 54. Then, multiply the base by the height of the rectangle to get the area. You can quickly add those up to discover your room needs 336 square feet of paint coverage. To quickly calculate the area of a rectangle, find the length of the base. Calculate the area of the rectangle carpet.A r e a = 12 m 2 area=12 96 f t 2 Solution : The length of the garden = 250 meterĪrea of the rectangular garden = 250 x 175Įxample 5: In an auditorium the floor is covered with a rectangular carpet, which is measured 9 m in length and 6 m in width. So the area of the white portion = 300cm² - 50cm² = 250cm².Įxample 4: The length of a rectangular shaped garden is 250 meters and then the width of the garden is 175 meters. Īnd the area of the violet colored rectangle = 10cm x 5cm = 50cm². So the area of the paper is = 20cm x 15cm = 300cm². Here the given paper has the shape of a rectangle. This Section will discuss the calculation of some of the most common surface areas: the triangle, the square, the rectangle, the rhombus, the parallelogram. Solution : We know that area of a rectangle is length × width. The area of a rectangle is the length on the side times the width. Sometimes, instead of length and width, the dimensions are called base and height. Find the area of the violet colored portion and area of white portion. You cannot multiply feet times inches, it doesnt make a square measurement. Jack has drawn a rectangle in the center of the paper which is 10 cm in length and 5 cm in width and painted the entire rectangle in violet color. Since the given length and width are in cm, the unit for area will be cm 2. Hence:Įxample 2: Find the area of the garden, length and width of the garden are respectively 600m and 400m.Įxample 3: A white paper has a size of length 20 cm and width 15 cm. We get the area of a rectangle by multiplying the length with the rectangle’s width. Now, the calculated number 15 only has a meaning if we include the unit for it. The area of a rectangle is always given in unit square (a number to the power of 2), whereas the perimeter is not. After doing so, we can calculate A, as shown below: Similarly, since the width is given as 3cm, we can substitute W with 3. Since the length is given as 5cm, we can substitute L with 5. Solution : To calculate the area, we can use the formula for the area of a rectangle: Frequently Asked Questions What is the Definition of Area The area of a two-dimensional shape is the amount of space it covers within its boundary. Let us consider a rectangle with length x units and width y units.Įxample 1: Given a rectangle where the length is 5cm and the width is 3cm. Also in a rectangle all the adjacent sides are perpendicular.Ī rectangle is a quadrilateral and also a parallelogram. In a rectangle all opposite sides are parallel and equal. Visual in the figure below: Despite the simplicity of the above equation, in specific situations you may not know these two exact measurements. A quadrilateral is a called rectangle, if it is a parallelogram and each angle measures 90 degrees.Ī rectangle is a four sided and closed figure. How to Calculate the Area of a Rectangle If you need to find the area and perimeter of a rectangle, this calculator is the handy tool you will need. The formula for the area of a triangle is height x x (radius / 2)2, where (radius / 2) is the radius of the base (d 2 x r), so another way to write it is height x x radius2.
