Answer 1

We know that

• The scale is 1 inch = 35 feet.

,

• Her model is 4 inches long and 1 inch wide.

To find the actual area, first, we find each actual dimensions by just multiplying.

`\begin{gathered} l=4\cdot35=140 \\ w=1\cdot35=35 \end{gathered}`

Then, we multiply the dimensions to find the actual area of the base.

`A=l\cdot w=140\cdot35=4900ft^2`

Hence, the area is 4,900 square feet.
