Question

The formula a=46c gives the floor area (a) in square meters that can be wired using (c) circuits

a. Solve a=46c for c
b. If a room is 322 square meters, how many circuits are required to wire this room? worked out

Answer 1

 a = 46c....for c
a/46 = c

322 = 46c
322/46 = c
7 = c.....7 circuits are required
