Rectangle Dimensions and Perimeter

The video tutorial explains how to calculate the perimeter of a rectangle and its stretched version. Initially, the rectangle is 3 meters long and 4 meters wide. The length is stretched four times, and the width is stretched three times. The original perimeter is calculated as 14 meters. The stretched perimeter is calculated as 48 meters. The difference between the original and stretched perimeters is found to be 34 meters.

What are the original dimensions of the rectangle?

• 4 meters long and 5 meters wide

• 4 meters long and 3 meters wide

• 3 meters long and 4 meters wide
