Question

On an architect's blueprint, 1 inch corresponds to 2 feet. Find the length of a wall represented by a line 6 1/2 inches long on the blueprint. Round to the 2nearest tenth if necessary.

Answer 1

Given:

On an architect's blueprint, 1 inch corresponds to 2 feet.

We will find the length of a wall represented by a line 6 1/2 inches on the blueprint

So, using the ratio and proportions:

Length on the blueprint : Actual length

1 : 2

6 1/2 : x

Using the cross multiplication:

x = 2 * 6 1/2 = 13 feet

So, the answer will be the length of the wall = 13 feet
