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. Now, the calculated number 15 only has a meaning if we include the unit for it. 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: 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. The area of a rectangle paper of 45 square inches and a width of 5 inches.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. The area of a rectangle rug 28 square feet and a length of 7 feet. The area of a square is 25 square centimeters. ANSWER BOX: A = in 2Ī rectangular yard has a length of 12 meters and a width of 4 meters. 1.įind the area of a square with each side measuring 6 inches. This will help you practice finding the area of a rectangle. After you click ENTER, a message will appear in the RESULTS BOX to indicate whether your answer is correct or incorrect. Your answers should be given as whole numbers greater than zero. Click once in an ANSWER BOX and type in your answer then click ENTER. The formula for area of a rectangle is:Ī = L * W where L is the length and W is the width.Ī square is a rectangle with 4 equal sides The formula for area of a square is:ĭirections: Read each question below.
Given the area and one dimension of a rectangle, we can find the other dimension. Given the length and width of a rectangle, we can find the area. Summary: The dimensions of a rectangle are length and width. So must equal 3 cm.Įxample 4: The area of a rectangle is 12 square inches and the width is 3 inches. Let's look at some examples in which we are given the area of the rectangle, and are asked to work backwards to find the missing dimension.Įxample 3: The area of a square is 9 square centimeters. In Examples 1 and 2, we found the area of a recentangle given the dimensions of the rectangle. Let's look at some examples of finding the area of rectangles.Įxample 1: Find the area of a square with each side measuring 2 inches.Įxample 2: What is the area of a rectangle that has a length of 8 centimeters and a width of 3 centimeters?
Or where A is the area, s is the length of a side, and To find the area of a square, multiply the length of one side by itself. The formula is:Ī = L * W where A is the area, L is the length, W is the width, and * means multiply.Ī square is a rectangle with 4 equal sides. To find the area of a rectangle, multiply the length by the width. Area is measured in square units such as square inches, square feet or square meters. Area is 2-dimensional: it has a length and a width. Perimeter is 1-dimensional and is measured in linear units such as inches, feet or meters. To understand the difference between perimeter and area, think of perimeter as the length of fence needed to enclose the yard, whereas area is the space inside the yard. The area of a polygon is the number of square units inside the polygon.
