Answer:
B. 336 square feet
Explanation:
The larger rectangle has a width of 20ft and a length of 30ft.
Width of the walkway = 3 feet.
Since the walkway is around the garden, we subtract the width on both sides.
Therefore:
[tex]\begin{gathered} \text{The length of the garden }=30-(3+3) \\ =30-6 \\ =24ft \end{gathered}[/tex]
Similarly:
[tex]\begin{gathered} \text{The width of the garden }=20-(3+3) \\ =20-6 \\ =14ft \end{gathered}[/tex]
We then calculate the area of the garden.
[tex]\begin{gathered} \text{Area of the garden=Length}\times Width \\ =24\times14 \\ =336\text{ square feet} \end{gathered}[/tex]
The area of the garden is 336 square feet.
