Math Problem Statement

Jazlyn makes a scale drawing of a rectangular rug she is going to weave. The scale from the drawing to the actual rug is 5 cm to 1 ft. What are the dimensions of the actual rug based on the drawing that measures 25 cm by 16 cm?

Solution

The problem shows that Jazlyn is using a scale of 5 cm : 1 ft for her drawing of a rectangular rug. The dimensions of the rug in the drawing are given as 25 cm for the length and 16 cm for the width.

To find the actual dimensions of the rug, we need to convert the drawing measurements from centimeters to feet using the given scale.

Step-by-step solution:

  1. Length of actual rug: Length in feet=Length in cmScale (cm per ft)=255=5ft\text{Length in feet} = \frac{\text{Length in cm}}{\text{Scale (cm per ft)}} = \frac{25}{5} = 5 \, \text{ft}

  2. Width of actual rug: Width in feet=Width in cmScale (cm per ft)=165=3.2ft\text{Width in feet} = \frac{\text{Width in cm}}{\text{Scale (cm per ft)}} = \frac{16}{5} = 3.2 \, \text{ft}

Final Answer:

  • Length of actual rug: 5 feet
  • Width of actual rug: 3.2 feet
