Answer 1

To find the height of the building on the blueprint, you need to set up a proportion.

The scale on the blueprint is 1/4 inch represents 5 feet.

Let x be the height of the building on the blueprint.

Setting up the proportion:
1/4 inch / 5 feet = x / 55 feet

Cross multiplying:
5 feet * x = 1/4 inch * 55 feet

Simplifying:
5x = 55/4 inch

To solve for x, divide both sides by 5:
x = (55/4 inch) / 5

Simplifying further:
x = 11/4 inch

Therefore, the height of the building on the blueprint is 11 1/4 inches.

The correct response is A) 11 1/2 in.
