Answer:
44 inches
Step-by-step explanation:
The side length is the square root of the area:
A = s^2
121 in^2 = s^2
√(121 in^2) = s = 11 in
The perimeter of a square is 4 times the side length (since all four sides are the same length).
P = 4s = 4(11 in) = 44 in
The perimeter of the square is 44 inches.
240 in or 20 ft; Since the scale is 1:40, Every 1 spot on the scale is equal to 40. So 6 times 40 equals 240 in. or 20 ft
