Exploring Area and Perimeter of Rectangles

The video tutorial explains how to determine the dimensions of a rectangular table given its perimeter and area. The table is longer than it is wide, and both dimensions are whole numbers. The tutorial walks through the process of setting up equations for the perimeter and area, and then uses trial and error to test different factor pairs of 24 to find the correct dimensions that satisfy both conditions. The solution is found to be a width of 4 feet and a length of 6 feet.

What are the given conditions for the rectangular table?

• Perimeter of 24 feet and area of 20 square feet

• Both length and width are even numbers

• Length is less than the width

• Perimeter of 20 feet and area of 24 square feet
