Finding Missing Side Lengths in Rectangles

The video tutorial explains how to find missing side lengths of a rectangle using its perimeter. It begins by defining perimeter as the distance around a shape and demonstrates how to split the perimeter into halves to simplify calculations. The tutorial provides two examples: one with a rectangle having a perimeter of 10 units and another with a perimeter of 20 units. In each example, the known side lengths are used to determine the missing lengths, emphasizing the properties of rectangles where opposite sides are equal. The video concludes with a quick trick for finding missing side lengths when the perimeter and one side length are known.

What is the main goal of the lesson introduced at the beginning?

• To calculate the area of a rectangle

• To learn about different shapes

• To find the missing side lengths of a rectangle

• To understand the concept of volume

What does the perimeter of a shape represent?

• The area inside the shape

• The distance around the shape

• The volume of the shape

• The length of one side of the shape

Which property is true for the opposite sides of a rectangle?

• They are always different in length

• They are equal in length

• They are perpendicular

• They are parallel

How can the perimeter of a rectangle be used to find missing side lengths?

• By multiplying the perimeter by two

• By subtracting the area from the perimeter

• By dividing the perimeter by the number of sides

• By splitting the perimeter into halves

If a rectangle has a perimeter of 10 units and one side is 2 units, what is the length of the opposite side?

• 5 units

• 4 units

• 6 units

• 3 units

In the example with a perimeter of 10 units, what is the length of the longer side?

• 3 units

• 4 units

• 5 units

• 2 units

What is the length of the opposite side if one side of a rectangle is 3 units and the perimeter is 10 units?

• 4 units

• 3 units

• 5 units

• 2 units

If a rectangle has a perimeter of 10 units, what is the total length of the two shorter sides?

• 2 units

• 3 units

• 5 units

• 4 units

For a rectangle with a perimeter of 20 units and one side of 6 units, what is the length of the shorter side?

• 5 units

• 3 units

• 2 units

• 4 units

In the example with a perimeter of 20 units, what is the length of the longer side?

• 8 units

• 7 units

• 9 units

• 6 units
