Question

a scale drawing of a rectangular building is 4 inches wide and 5 inches long. the actual building is 240 yards wide. what is the area of the actual building in yards

Answer 1

72,000 yards

Explanation:

The scale factor can be found by doing:

`240 / 4 = 60`

This means that 60 is the scale factor. You can apply the scale factor to the length of the rectangular building, meaning that the length of the actual building is:

`5 \cdot 60 = 300` yards

So, if the building is 240 yards wide, and 300 yards long. You can find the area of the actual building just like any other rectangle using:

`A = l \cdot w`

(Area = length * width)

So, the final answer is:

`A = 300 \cdot 240\\ A= 72,000`

This means that the area of the actual building is 72,000 yards.
