Calculate metres squared11/21/2023 We will label the green rectangle R g, the red rectangle R r, and the half circle, C. The area is made up of two rectangular spaces and an area that is half a circle. This same concept applies to the area of any room we can find the area by calculating the area of all the individual shapes that make up the room, then find the sum.įind the area of the following space in square meters. If the room is made up of a number of rectangles, calculate the areas of each rectangle separately (using length × width), then find the sum of their areas. Many spaces are made up of rooms that are either not perfectly rectangular, or are made up of a number of rectangles. Simply fill the area with unit squares, and count the number of squares as best you can. It is possible to estimate the area of any space, even if it is not rectangular, using this method. Since the rectangle in the figure below is made up of 8 squares with an area of 1 m 2 each, it has an area of 8 m 2: We can easily see why the area of a 4 × 2 rectangle is 8 m 2 by breaking the rectangle down into unit squares. Multiply length and widthĪ 4 m × 2 m rectangle has an area of 4 × 2 = 8 m 2. The most straightforward way to measure square meters is to calculate the length and the width of the area, then multiply them, but this only works if the area is rectangular. A professional basketball court is 420 m 2.Below are some examples to help with visualizing how big a square meter is. How big is a square meterĪ square meter is the area formed by a square with side lengths of 1 meter. In the case of square meters, each length is measured in meters, so multiplying meters × meters results in meters 2. Square units of area, such as square meters, are a result of multiplying the two lengths. What is 1 square meterġ square meter is the area of a square with a side length of 1 m, as shown in the figure below:Ī square area is a measurement made up of two lengths. Home / primary math / area / square meters Square metersĪ square meter (m 2) is a measure of the area of a square with sides of 1 meter.
