Question

Tom is looking at plans for his new house. According to the plan, 2.6 inches equals 13 feet. If the length of the wall is 18 feet how long is the wall on the plan

Answer 1

If the length of the wall is 18 feet, then the wall on the plan is 3.6 inches long

Solution:

According to Tom,  2.6 inches equals to 13 feet

Length of the wall = 18 feet

If 2.6 inches is equal to 13 feet, then 1 feet is equal to:

$1 feet = \frac{2.6}{13} = 0.2 inches$

So, 1 feet = 0.2 inches …….(1)

Now, we have to determine the length of the wall on the plan which is 18 feet long

Using Equation (1), 18 feet = 18 × 0.2 inches = 3.6 inches

Hence , the wall on the plan is 3.6 inches long
