Question

Not sure how to figure this out.Options:A. 49 square feet B. 7 square feet. C. 28 square feet. D.14 square feet

Answer 1

According to the information given in the exercise, the pen for his rabbit is square and each side is 7 feet long.

You know that the formula for calculating the area of a square is:

`A=s^2`

Where "s" is the length of each side of the square.

In this case:

`s=7ft`

Then, you need to substitute this length into the formula and then evaluate, in order to find the area. You get:

`\begin{gathered} A=(7ft)^2 \\ A=49ft^2 \end{gathered}`

Hence, the answer is: Option A.
