Answer:
72 inches
21.3 inches
Step-by-step explanation:
Write a proportion:
height / width = 12 / 27
If height = 32 inches:
32 / width = 12 / 27
Cross multiply:
12 × width = 32 × 27
Solve for width:
width = 32 × 27 / 12
width = 72
If width = 48 inches:
height / 48 = 12 / 27
Cross multiply:
27 × height = 12 × 48
Solve for height:
height = 12 × 48 / 27
height = 21.3
