Calculating Area and Cost

The video tutorial explains how to calculate the total cost of fabric needed for three tablecloths. It begins by determining the area of one tablecloth using the formula for the area of a rectangle. The area is then multiplied by three to find the total area for all tablecloths. Finally, the cost is calculated by multiplying the total area by the cost per square foot of fabric. The tutorial provides a step-by-step guide to solving the problem, including converting mixed numbers to improper fractions and simplifying before multiplication.
