Application Problems In the figure below, you can see how linear dimensions are represented. Sometimes the dimension is listed inside the two markers along with the arrows that define that linear distance… such is the case with the 20 in. measurement. 20 in 4 in

Application Problems In the figure below, you can see how linear dimensions are represented. Sometimes the dimension is listed inside the two markers along with the arrows that define that linear distance… such is the case with the 20 in. measurement. 20 in 4 in There are other cases where the arrows and dimension value are too big to fit into the space. So the dimension value will appear inside, and the arrows will appear outside and squeeze in towards the dimension’s value.

Application Problems Some figures will have holes shown. The holes will have the center marked with a plus sign, and lines extending from that center out a little beyond the edge of the circle.
