'a 2 ' means 'a squared', which is the same as 'a' times 'a'. Calculate the area of the rectangle carpet. Area Formulas Note: 'ab' means 'a' multiplied by 'b'. By counting the number of squares in a region, you can find the area of that region. 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. Area using formulas for square and rectangle - Perimeter and area. So the area of the paper is = 20cm x 15cm = 300cm². Here the given paper has the shape of a rectangle. Solution : We know that area of a rectangle is length × width. Find the area of the violet colored portion and area of white portion. 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. Example: What is the area of this rectangle The formula is: Area w × h w width h height The width is 5, and the height is 3, so we know w 5 and h 3: Area 5 × 3 15 Learn more at Area of Plane Shapes. Now, the calculated number 15 only has a meaning if we include the unit for it. 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. ![]() After doing so, we can calculate A, as shown below: In Section 1.2 we introduce some simple motivating examples of functional equations, such as the formula for the area of a rectangle, the simple interest. The area of any rectangular place is or surface is its length multiplied by its width. 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: 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. ![]() ![]() To find out what the number is, we just divide both sides by 3 to get: Therefore the height of an. Next, find the base of the rectangle that goes from 4 to 7 by subtracting: Next, plug in what we know into the area equation: This tell us that 3 times a number is equal to 1. Also in a rectangle all the adjacent sides are perpendicular.Ī rectangle is a quadrilateral and also a parallelogram. First sketch the rectangle below, labeling the height as. In a rectangle all opposite sides are parallel and equal. Its like counting how many squares you can fit inside the rectangle Formula of Area of a Rectangle The area of a rectangle is like the space it covers inside its four sides, kind of like a yard surrounded by a fence. 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. We can find the area by multiplying the length and the width together.
