A rectangular lot area is illustrated below. Inside the perimeter of the rectangular lot are three circular areas that will be concreted, Each circular lot is having a radius of AB, CD. and EF, which were measured by the use of pacing Listed are the number of steps to measure the radius of each circular lot considering that the pace factor of the surveyor is 0.86. Calculate the area that will not be concreted in unit squared. AB CD EF 155.55 78.85 157.77 158.65 77.9 158.78 158.54 78.84 158.76 156.87 78.8 157.86 156.88 78.45 155.68 158.97 78.54 157.84 157.77 77.96 157.48 156.77 77.36 156.77 157,46 77.69 157.77 157.84 78.45 158.97 155.68 76.84 156 88 157.86 78.8 156 87 158,76 78.96 158.54 158.78 76.87 158.65 157.77 78.87 155.55

Length and Length related Variables

Length can de defined as the measurement or extent of physical quantities or objects from one terminal to another terminal. Stone age humans used finger length, step length, and so on to measure the size or displacement of an object. Nowadays, depending on how precise the measurement requires to be and the object’s size is measured, we use measuring devices for measurements like rulers and steel tape. Most people have used a ruler or tape measure to measure a particular distance or the size of an object. For more precise measurements of tiny objects, the development of measurement tools such as the Vernier caliper, which permits us to measure dimensions within 1/1000 of an inch. In the last few decades, electronic distance measuring instruments (EDMI) have been implemented that permit us to measure distances from a few feet to many miles with reasonable accuracy.
