Question

Omar measured a house and its lot and made a scale drawing. The backyard deck, which is 42 feet long in real life, is 105 inches long in the drawing. What scale did Omar use? 5 inches : feet

Answer 1

5 inches: 2 feet

Explanation:

Since Omar's 42 feet long deck is 105 in. on his drawing and we know his scale is 5 in. for every x feet, we can determine how much feet is equivalent to 5 in. on his scale using a proportion:

42 ft / 105 in. = x ft / 5 in.

42/105 = x/5

(2/5 = x/5) * 5

10/5 = x

2 = x

Thus, 5 inches represents 2 feet on Omar's scale.
