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 <====
