Use a ruler to make a right angle triangle of dimension 3,4,5 the angle adjacent to the side of 4 units length is 30 degrees.
It is: 0.5*3*4 = 6 square feet
Area of triangle: 0.5*3*4 = 6 square feet
Length IS a dimension (in space). It has no thickness.
Lines that define the parameters of a dimension.Dimension lines are thin lines terminating in arrowheads. Place dimension lines no closer than 3/8" from the object outline. Parallel dimension lines should be a minimum of 1/4" apart. You may place parallel dimension lines more than 1/4" apart so long as the spacing between dimension lines is uniform throughout the drawing. Dimension lines are generally broken in the center of the line to provide a space for the dimension figure. Dimension figures for parallel dimension lines are staggered. In some structural or architectural drawings, you may find dimension figures placed above the dimension line.

The graduation of an angle would usually be expressed in degrees, of which there are 360 for a complete circle.
No, a plane angle does not have a dimension in the sense of length, area, or volume. It is a measurement of rotation or orientation between two intersecting lines in a plane.
Height or altitude.

Messier 14 or NGC 6402 has an apparent dimension of 11 minutes of arc.
It is angular displacement which may be measured in radians, or degrees-minutes-seconds. In 3-D it would be stradians
isometric drawing create the illusion of 3 dimension by drawing the depth of the object on the both side.. in isometric drawing they are both set on the 30 degree angle..
An XY intercept is the point that lays in a two dimensional plane where a line representing an X dimension in that plane and a transverse line at a right angle representing a Y dimension in the same plane intersect.
It is: 0.5*3*4 = 6 square feet
