It takes 24 feet of fence to surround a square piece of land in sam's backyard. sam wants to plant flowers everywhere but on the diagonal sidewalk (shaded in the diagram attached). note that there is 1 foot of sidewalk along two sides of the square as indicated in the diagram attached. what is the area of the sidewalk?

Option B. 5.5 ft²

Step-by-step explanation:

Perimeter of the square piece of land = length of fence required

4(length of a side of the square) = 24 ft

Length of a side = 6 ft

Area of the square land = (Side)²

= 6²

= 36 square ft

Area of the side walk = Area of the square - [Area of two triangles separated by the sidewalk]

= 36 - []

= 36 - []

= 36 - (18 + 12.5)

= 36 - 30.5

= 5.5 ft²

Therefore, Option B. is the correct answer.
