People ask also, how do you **measure** irregular area? To find the Area of **Irregular** Shapes, first, we need to divide the Irregular Shape into Regular Shapes that you can recognize such as triangles, rectangles, circles, Squares and so forth. Then, find the Area of these individual Shapes and add them to get an Area of Irregular Shapes.

Also the question is, how do you measure **area** in **Autocad**? Right-click and choose Properties. Properties of the selected object, including the **area**, are displayed. Note: Unlike individual lines, polylines are considered closed objects and always have a calculated **area**. Or at the Command prompt, type aa (AREA).

In this regard, how do you find the area of different shapes?

- Square area formula: A = a²
- Rectangle area formula: A = a * b.
- Triangle area formulas: A = b * h / 2 or.
- Circle
**area**formula: A = πr² - Circle sector area formula: A = r² * angle / 2.
- Ellipse
**area**formula: A = a * b * π - Trapezoid
**area**formula: A = (a + b) * h / 2. - Parallelogram area formulas:

Considering this, how do you find the area when all sides are different? The area of any **irregular** quadrilateral can be calculated by dividing it into triangles. Example: Find the **area** of a quadrilateral ABCD whose sides are 9 m, 40 m, 28 m and 15 m respectively and the angle between the first two sides is a right angle. The area of the quadrilateral ABCD =(180+126)=306 square meters.

- Click Home tab Utilities panel Measure drop-down Area. Find.

## How does AutoCAD calculate multiple hatch areas?

- Area of multiple hatch objects can be found by typing list command, and selecting hatch objects.
- Alternatively, if hatch objects are selected using grips, then Properties palette will show the area (for single hatch object) and cumulative area (for multiple objects) under “Geometry”.

## How do you find the area of a three dimensional shape?

Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.
