 a. 5√3 ft

 b. 8.7 ft

Step-by-step explanation:

The area is the square of the side length, so the side length is the square root of the area:

  s = √A

  s = √(75 ft²) = √(25·3 ft²) = √(3·(5 ft)²)

  s = 5√3 ft ≈ 8.7 ft . . . . . . side length of garden

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.
