Garden fencing

The garden has the shape of a rectangle with dimensions of 32 m and 29 m. We must fence it all off, except for the entrance gate, which will be 4 m long. What is the size of the garden?

Final Answer:

o =  118 m
S =  928 m²

Step-by-step explanation:

$$\begin{gathered} a=32\text{m} \\ b=29\text{m} \\ c=4\text{m} \\ o=2\cdot a+2\cdot b-c=2\cdot 32+2\cdot 29-4=118\text{m} \end{gathered}$$

$S=a\cdot b=32\cdot 29=928{\text{m}}^2$
