Question 2. Below shown is the profile for a road construction at a station. This is a fill section. Sometimes the letter C is used to designate cut and F to indicate fill for the vertical distance or depth. In other words, a point below the base would have a negative sign in a fill section. F 11.8 below corresponds to -11.8 ft. The baseline is 50ft. Calculate the area for the fill section. (Answer: 137.3 yd²) 50ft F 11.8 -42.5 F 14.3 -32.0 0 -25 25 olo F 15.8 25 25 Baseline F 16.3 65.4
