A rectangular advertisement is 144 inches wide and 42 inches long. A media company wants to create a billboard advertisement using a scale factor of 4.

Part A: What are the dimensions of the billboard in feet? Show every step of your work.

Answer :

Using the scale factor of 4, the dimensions of the billboard advertisement are 48 feet x 14 feet.

The problem can be solved using dilation concept.

The scale factor in a dilation is the ratio of the lengths of any two corresponding sides of the original figure and its image after dilation.

The dimensions of the billboard advertisement can be found by multiplying the original dimensions by the scale factor of 4.

Step 1: Multiply the width by the scale factor: 144 inches x 4 = 576 inches
Step 2: Multiply the length by the scale factor: 42 inches x 4 = 168 inches
Step 3: Convert the dimensions from inches to feet: 576 inches ÷ 12 = 48 feet, 168 inches ÷ 12 = 14 feet

Hence, the dimensions of the billboard advertisement in feet are 48 feet wide and 14 feet long.
