Video Summary

Jessica cuts out four identical squares from a square sheet of paper, with each square having an area of 4 square centimeters, making their side lengths 2 centimeters. The original sheet's area is 25 square centimeters, as deduced from adding the cut area (16 cm²) and the remaining cross's area (9 cm²), giving it side lengths of 5 centimeters. After figuring the dimensions, the cross's perimeter is calculated using four 1-centimeter sides (totaling 4 cm) and eight 2-centimeter sides (totaling 16 cm), resulting in a total perimeter of 20 centimeters.
