Question

The above diagram is a section of the bridge. A,B,C,D,E,F and G are vertical supports. The vertical support A = 10 meters long. ALSO: length A = G, Length B= F and Length C = E. The length of B is 3/5 of A. The length of C is 4/5 of B. The length of D is 9/10 of C. Calculate the total lengths of the supports.

Answer 1

You just need to use the given information to retrieve all the lengths:

• A is given
• B is 3/5 of A. Multiply the length of A by 3/5 and you'll get B
• C is 4/5 of B. Multiply the length of B by 4/5 and you'll get C
• D is 9/10 of C. Mulply the length of C by 9/10 and you'll get D
• E is the same as C, which we already got
• F is the same of B, which we already got.
