the diagram is a floor plan for a new building. find the perimeter.
162
152
154
144

Explanation:

Step1: Calculate the missing vertical side

The total vertical side on the left is \(18\). The middle - missing vertical part: \(18-(14) = 4\). The total height of the right - hand side can also be calculated. The sum of the vertical sides: \(18+14 + 9+13\) (by moving the horizontal and vertical segments to form a more regular shape for perimeter calculation).

Step2: Calculate the missing horizontal side

The total length of the bottom side is \(80\). The sum of the top - side horizontal segments: \(16 + 20+16\). The sum of all horizontal sides: \(80 + 80\) (since the bottom and top horizontal lengths are equal when considering the perimeter concept of moving segments). The sum of all vertical sides: \(18+14 + 9+13+(18 - 14)+(18 - 13)\) (by using the property of perimeter that the sum of vertical sides on the left and right is equal when we translate the inner - vertical segments). In a simpler way, using the perimeter formula for a "rectangle - like" shape after segment translation:
The perimeter \(P=2\times(80)+18 + 14+9+13+(18 - 14)+(18 - 13)\)
Another way:
The sum of the horizontal lengths: \(80+80\) (bottom and top). The sum of the vertical lengths: \(18+(18 - 14)+14+9+(18 - 13)+13\)

$$P = 2\times80+2\times18+14 + 9+13-14 - 13$$

$$P=160 + 36$$

$$P = 152$$

Answer:

\(152\)
