Answer:


91\operatorname{cm}^2

Step-by-step explanation:

Step 1. The information that we have about the regular heptagon is:

The apothem, which we will call ''a'':


a=5.2cm

The perimeter, which we will call ''P'':


P=35cm

Step 2. The formula to find the area of any regular polygon (in this case a heptagon) is:


A=(P* a)/(2)

Where A is the area, P is the perimeter and a is the apothem.

Step 3. Substitute the values of P and a into the formula:


A=(35cm*5.2cm)/(2)

Solving the operations we find the area:


\begin{gathered} A=(182cm^2)/(2) \\ \\ A=\boxed{91\operatorname{cm}^2} \end{gathered}

Answer:


91\operatorname{cm}^2
