The tall of the actual building will be 216 feet
Step-by-step explanation:
An architect is presenting a scale model of a building she's designed
to the planning committee of college
1. The scale of the model is 1 inch = 18 feet
2. The tallest wall in the model is 12 inches
3. We need to know how tall the actual building will be
Let us used the ratio method
∵ The scale of the model is 1 inch represents 18 feet
∵ The tallest wall in the model is 12 inch
→ Model(in) : Actual(ft)
→ 1 : 18
→ 12 : h
- By using cross multiplication
∴ 1 × h = 12 × 18
∴ h = 216 feet
∴ The actual height is 216 feet
The tall of the actual building will be 216 feet
