What is the total center line length for the plan shown if the thickness of walls is 30 cm?' Correct Answer 34.1 m

In centre line methods, lengths are measured from center line of walls and all windows, doors are included in this method.

Length, AB = 0.15 + 4 + 0.3 + 3 + 0.15 = 7.6 m

Length, CD = AB = 7.6 m

 Length, BC = 6 + 0.15 + 0.15 = 6.3 m

Length, AD = BC = 6.3 m

Length, EF = 6 +0.15 + 0.15 = 6.3 m

Total Center line length = AB + BC+ CD + DA + EF

Total Center line length = 7.6 + 6.3 + 7.6 + 6.3 + 6.3

∴ Total Center line length = 34.1 m

Given are the steps to draw a perpendicular to a line from a point outside the line, when the point is near an end of the line. Arrange the steps. Let AB be the line and P be the point outside the line i. The line ED is perpendicular to AB ii. Now take C as centre and CP as radius cut the previous arc at two points say D, E. iii. Join E and D. iv. Take A as center and radius AP draw an arc (semicircle), which cuts AB or extended AB at C.
