Area is the space covered by a two-dimensional shape. The two dimensions are often expressed in terms of length and height or length and width. Multiplying length by height gives the area of rectangular objects. If these objects are measured in feet, the area is in square feet.Continue Reading
Two perpendicular measurements are needed to calculate the area of most shapes. On a rectangle, measuring the sides can give you the dimensions you need because one side can be the length and the adjacent side can be the height. On many other shapes, measuring one or more flat sides and then the height (or greatest distance taken with a perpendicular line) often works.
For rectangles, multiply the length (or base) by the width (or height). The units are also multiplied. For example, if you measured a wall at 12 feet long by 8 feet high, the area would be 96 square feet. Use the appropriate formula for the shape. For example, the area of a triangle is the height multiplied by the base and divided by two; the area of a circle is the radius squared multiplied by pi. If the shape is irregular, you may have to calculate the area in segments.
If you were working with units other than feet, convert the area to square feet. For example, if you used inches to measure the sides of the object, divide the resulting measurement in square inches by 144 to obtain the area in square feet.
To calculate the area in square yards of a square or rectangular shape, multiply the length by the width. If the dimensions of the shape are not given in yards, it is necessary to convert it first. An explanation for converting one unit to another is available from MathIsFun.com.Full Answer >
To calculate area, first determine the shape of the object. Next, apply the correct formula is needed, and substitute the values into the appropriate places. Finally, the equation should be solved to find the number that represents the area.Full Answer >
In math, area represents the size or total amount of space taken up by a two-dimensional surface, or the amount of space inside the boundaries of a flat object. The area may be measured in a variety of square units, such as inches, feet and meters.Full Answer >
Geometry is defined as the area of mathematics dealing with points, lines, shapes and space. Geometry is important because the world is made up of different shapes and spaces. It is broken into plane geometry, flat shapes like lines, circles and triangles, and solid geometry, solid shapes like spheres and cubes.Full Answer >
