The video tutorial explains how to find the missing side length of geometric figures given their perimeter. It starts with a figure having a perimeter of 24 cm, where the known side lengths are added to find the missing side. The process involves adding known lengths and determining the remaining length needed to reach the total perimeter. The tutorial then moves to a rectangle with a perimeter of 32 meters, where one side is known, and the opposite sides are equal. The missing side lengths are calculated by dividing the remaining perimeter equally between the two unknown sides.

What is the perimeter of a figure?

• The area inside the figure

• The distance around the figure

• The length of one side of the figure

• The width of the figure

How do you find the missing side if the perimeter is known?

• Subtract the sum of known sides from the perimeter

• Subtract the known sides from the area

• Add all the known sides

• Multiply the known sides

In a rectangle, if one side is 11 meters, what is the length of the opposite side?

• 11 meters

• 32 meters

• 22 meters

• 5 meters

How do you calculate the missing sides of a rectangle when the perimeter and one side are known?

• Subtract twice the length of the known side from the perimeter and divide the result by 2

• Add the length of the known side twice from the perimeter and divide by 2

• Subtract the known side from the perimeter

• Divide the perimeter by the known side
