Answer:
The width of Jonesha's backyard is 45 feet.
Explanation:
Given that Jones has made a scale of her backyard, which was 6 inches long and 9 inches wide, if the actual length was 30 feet, to determine the real width of her backyard, the following calculation must be performed:
1 ft = 12 inches
30 ft = 30 x 12 = 360 inches
360/6 = 60
Thus, the scale of Jonesha's backyard is 1:60. Therefore, the real width of the backyard of it arises from the following calculation:
(9 x 60) / 12 = X
540/12 = X
45 = X
Thus, the width of Jonesha's backyard is 45 feet.
