2. A survey line AB crosses a river obliquely. P and Q are two points selected on the line one at each end of the river. Another line EPF is run parallel to the centre line of the river and point E is such that angle QEP is right angle and EP = PF = 100 m. A third point G is set at a distance of 150 m from P such that angle GFP is also right angle. Compute the distance PQ. 100 370

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.
