Calculating Perimeter of Rectangles

The video tutorial explains how to find the perimeter of a rectangle by adding the lengths of all four sides. It details the specific lengths of the rectangle's sides, which are 4 and 1/2 centimeters and 2 and 1/4 centimeters. The tutorial then walks through the calculation process, showing how to add these lengths to find the total perimeter, which is 13 and 1/2 centimeters.

What is the first step in finding the perimeter of a rectangle?

• Multiply the lengths of all sides

• Add the lengths of all four sides

• Subtract the lengths of the shorter sides from the longer sides

• Divide the total length by four

Why are opposite sides of a rectangle equal in length?

• Because they are parallel

• Because they are perpendicular

• Because they are diagonals

• Because of the properties of a rectangle

If one side of a rectangle is 4.5 cm, what is the length of the opposite side?

• 9 cm

• 4.5 cm

• 2.25 cm

• Cannot be determined

What is the length of the shorter side of the rectangle in the example?

• 3 cm

• 5 cm

• 2.25 cm

• 4.5 cm

How do you simplify the sum of 2 and a quarter plus 2 and a quarter?

• 4

• 4 and 1/2

• 5

• 4 and 2/4

What is the sum of 4 and a half plus 4 and a half?

• 9.5

• 10

• 9

• 8

What is the simplified form of four and two quarters?

• 4

• 5

• 4 and 1/2

• 4 and 1/4

What is the perimeter of the rectangle in the example?

• 12 cm

• 13 cm

• 13.5 cm

• 14 cm

What is the final step in calculating the perimeter of the rectangle?

• Adding the whole numbers and fractions separately

• Subtracting the fractions

• Multiplying the whole numbers

• Dividing the total by two

How do you calculate the perimeter of a rectangle with sides 4.5 cm and 2.25 cm?

• Multiply 4.5 by 2.25

• Subtract 2.25 from 4.5

• Add 4.5 and 2.25 and multiply by 2

• Add 4.5 and 2.25
