Question

The area of the 4 walls of a room is 77msq the length and breadth of the room are 7.5m and 3.5m respectively find the height of the room

Answer 1

Formula is 2(l+b) * h

                2(7.5 + 3.5) * h = 77

                2(11) * h = 77

                  22h = 77

                      h = 77/22

                         = 3.5
