AREA command:
Select Object from this prompt and click on the boundary of Rectangle or Circle for which you want to find the area. The area

of the object will appear above command line along with its perimeter or circumference. In a similar way, you can find the

area of any closed Polyline geometry with AREA command.
Solution
Enter HATCHEDIT on the command line.
Select the hatch.
In the Hatch Edit dialog box, click Recreate Boundary.
When you see the prompt "Enter type boundary object", enter P for polyline or R for region.
When prompted, choose whether or not to associate the hatch with the new boundary.
Enter OPTIONS in the command line. On the Drafting tab. Under Object snap options.

Solution:
Turn off or freeze any hatch layers with hatch patterns so they are not included in the selection.
Type FLATTEN at the command line.
Select all objects and press the Enter key.
Type N for No when prompted to remove hidden lines.
Help

How to measure the distance and angle between two points ? Press the Distance button, and tap the canvas or double tap line.

Tap to specify the first point and then drag or tap again to specify the end point. The fields in the measuring toolbar will

be updated with the measurement data.
To find the area, multiply the base by the height, and then divide that number by 2. How do you measure a triangle? Start by

measuring the length of the base of the triangle. The height is the line perpendicular to the base, through the opposite

vertex.
The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle

multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same

length) and then multiply this by itself to find the area.
These contour lines are an important way of showing the rise and fall of the land on a map. Contour lines show all the places

that are the same height above sea level. They also tell us about the slope of the land. On a steep slope, the lines are

close together.
Other characteristics of contour lines are:
- Horizontal distance between contour lines is inversely proportional to slope. - Uniform slopes have uniformly spaced lines.

- Along plane surfaces, contour lines are straight and parallel. - Contour lines are perpendicular to lines of steepest

slopes.
nswer and Explanation:
Contour lines never cross on a topographic map because they represent the same elevation of the land. A particular point of

land cannot be at more than one elevation, so only one contour line will pass through that spot.
There are times when you need to find the area of a shape that is not a regular shape. One method for finding the area of an

irregular shape is to divide the shape into smaller shapes which you do have the formula for. Then you find the area of all

of the smaller shapes and add all of your areas together.
