Question

on a scale drawing, a rectangular area has a length of 25 feet and a width of 12 feet. the length of the actual rectangular area is 250 feet. what is the width of the actual rectangular area?
○ 29 feet
○ 120 feet
○ 300 feet
○ 520 feet

Explanation:

Step1: Find the scale factor

The scale drawing length is 25 feet, and the actual length is 250 feet. The scale factor \( k \) is the ratio of actual length to drawing length. So \( k=\frac{250}{25} = 10\).

Step2: Calculate the actual width

The drawing width is 12 feet. To find the actual width, multiply the drawing width by the scale factor. So actual width \(=12\times k = 12\times10=120\) feet.

Answer:

120 feet (corresponding to the option "120 feet")
