Answer:

40 ft

Step-by-step explanation:

We can use ratios to solve this problem.  Put the scale over the actual size

1/4 inch           2 inches

-------------- = ----------------

5 ft                  x ft

Using cross products

1/4 x = 2 *5

1/4 x = 10

Multiply each side by 4

4*1/4 x = 4 * 10

x = 40

The wall is 40 ft
