What is Area?
Area is how much space a figure takes up. This is important information to know because we need to be able to "budget" space when dealing with furniture and other objects. Area is one of those math skills that you need for everyday life. Finding area for quadrilaterals is-in my opinion-easiest. The formula for quadrilaterals is simply length x height=area. The formula for triangles is base x height÷2=area. When a figure is complex, you can break it into rectangles, triangles, and circles. Then you add the areas of all the pieces together to get the total area.
Here are some figures that you can find the area of. I'll help you out with the first one. These are the answers.
1)
The first thing you want to do with this figure is split it up. The easiest way to do that with this figure is to cut it into a rectangle and a triangle.
Let's find the area of the rectangle first. 9 x 12 = 108 So, the area of the rectangle is 108 ft.²
Now let's find the area of the triangle. This is trickier. In order to find the base of the triangle,
you subtract 12 from 18. The base of your triangle is 6 ft.. 6 x 9 ÷ 2 = 27 So, the area of the
triangle is 27 ft.² 108ft² + 27ft² = 135ft² The area of the entire figure is 135ft.².
