lesson 10 practice problems

1. here is a scale drawing of a swimming pool where 1 cm represents 1 m.

a. how long and how wide is the actual swimming pool?

Explanation:

Step1: Measure length on drawing

Use a ruler to measure the length of the rectangle representing the pool on the scale - drawing in centimeters. Let's assume the measured length is $l_{d}$ cm.

Step2: Convert length to actual length

Since 1 cm on the drawing represents 1 m in reality, the actual length $L$ of the swimming - pool is $L = l_{d}\times1$ m.

Step3: Measure width on drawing

Use a ruler to measure the width of the rectangle representing the pool on the scale - drawing in centimeters. Let's assume the measured width is $w_{d}$ cm.

Step4: Convert width to actual width

Since 1 cm on the drawing represents 1 m in reality, the actual width $W$ of the swimming - pool is $W = w_{d}\times1$ m.

Answer:

The actual length is the measured length in cm on the drawing (in meters) and the actual width is the measured width in cm on the drawing (in meters). You need to measure the length and width of the rectangle on the given scale - drawing to get the specific values.
