if one inch represents 12 feet ,what dimentions whould you use to make a scale drawinng of a building 75 feet by 80 feet?
alina1380 [7]

Answer:

Step-by-step explanation:

1 inch to 12 ft = x inches to 75 ft

1 / 12 = x / 75

cross multiply

12x = 75

x = 75/12

x = 6.25 or 6 1/4 inches

1 inch to 12 ft = x inches to 80 ft

1 / 12 = x / 80

cross multiply

12x = 80

x = 80/12

x = 6.67 or 6 2/3 inches

so the dimensions are : 6 1/4 inches by 6 2/3 inches <====
