Responses

Answer 1

To find the height of the building on the blueprint, we can set up a proportion using the scale given:

2 inches / 30 feet = x inches / 120 feet

Cross-multiplying, we have:

2 * 120 = 30 * x

240 = 30x

Dividing both sides by 30:

x = 8

Therefore, the height of the building on the blueprint is 8 inches.
