Answer:
v= 141.37
Step-by-step explanation:
π · 3^2 · 15/ 3
=141.37167
Imagine a rectangular area that represents the garden. Then, add a uniform margin of 2 ft around it. So, the length and width dimensions of the bigger outer rectangle would be added with 4 ft each, accounting for two 2-ft marginal distances on both ends. This would be the perimeter:
2(L+4) +2(W+4) = 46
Since L = 2W
2(2W +4) + 2(W+4) = 46
4W + 8 +2W + 8 = 46
W = 5 ft
L = 2(5) = 10 ft
Therefore, the dimensions of the garden is 10 ft in length and 5 ft in width. The area, consequently, is calculated as:
A = LW
A = (10 ft)(5 ft)
A = 50 ft²
Thus, the area of the garden is 50 ft².
