Step-by-step explanation:
Since the land is a round enclosure, and it has 2.5 foot wide enclosure of pebbles surrounding, then the circumference of the garden is 2.5ft.
First we need to get the diameter of the garden using the formula;
Circumference= πd
2.5 = πd
d = 2.5/π
d = 2.5/3.142
d =0.796 feet
The total area of a round section of the land = πd²/4
The total area of a round section of the land = π(0/796)²/4
The total area of a round section of the land = 1.9892/4
<em>The total area of a round section of the land = 0.4973 ft²</em>
