A 12-toot wall measures 2.5 inches on a
scale drawing. In the drawing, a second
wall is 9 inches long. What is the actual
length of the second wall?


Sagot :

Answer:

actual length of the second wall is 43.2 ft

Step-by-step explanation:

Let x be the actual length of the second wall

Write measurements in ratios with feet to inches:

First wall:      12 : 2.5 = 12/2.5

Second wall:      x : 9 = x/9

Equate the two fractions and solve for x:

12/2.5 = x/9

Multiply both sides by 9:  43.2 = x

Therefore, the actual length of the second wall is 43.2 ft
