The question provides two rectangles, one is a scale model while the other one is the actual figure.

The scale is given as;


1\operatorname{cm}\colon7m

This means, for every centimeter on the model rectangle, the actual rectangle would be 7 meters. Therefore 2 centimeters on the model would be 7 times 2 meters on the actual rectangle.

Hence, the dimensions of the actual rectangle would be;


\begin{gathered} L=6*7(\text{meters)} \\ W=4*7(\text{meters)} \\ \text{Therefore,} \\ L=42m,W=28m \end{gathered}

The area of the actual rectangle therefore would be;


\begin{gathered} A=L* W \\ A=1176m^2 \end{gathered}

ANSWER:

The area of the rectangle is


1176m^2
