Show the math

Perimeter = 2 × (50 + 30) = 160 ft
Walls = 160 × 9 ft × 1 story = 1,440 sq ft
Gables = 2 × ½ × 30 × 7.5 = 225 sq ft
Openings = 12 × 15 + 2 × 20 = 220 sq ft
Net wall area = 1,665 − 220 = 1,445 sq ft
Order area = 1,445 × 1.1 = 1,589.5 sq ft = 15.9 squares
Installed = 1,445 sq ft × $4–$12 × region 1 = $5,780 – $17,340
