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? 120 feet 300 feet 520 feet 29 feet

Explanation:

Step1: Set up proportion

Let the actual width be $x$. Since the ratio of scale - drawing length to actual length is the same as the ratio of scale - drawing width to actual width, we have the proportion $\frac{25}{250}=\frac{12}{x}$.

Step2: Cross - multiply

$25x = 12\times250$.

Step3: Solve for $x$

$x=\frac{12\times250}{25}=120$.

Answer:

A. 120 feet
