Question

Alfonso made a scale drawing of a tower. The actaul height of a tower is 25 feet. The scale Alfonso used in his drawing is 1 in.:10 ft. What is the height of the tower in Alfonso's drawing?

Answer 1

2.5 inches

Explanation:

Using Alfonso's scale of the drawing, which is 1in=10 ft, we can conclude the height of the tower to be 2.5 inches because

the actual height of the tower is 25 feet

10+10=20, which by following the scale, is 2 inches

we then have 5 left, 5 being half of 10, and .5 being half an inch.

Therefore the height of the tower using Alfonso's scale is 2.5 inches.

Hope this helps and take care
