Geometry: Area and Perimeter Concepts

This video tutorial covers the concepts of perimeter and area for parallelograms, rhombuses, and kites. It explains how to calculate the perimeter by adding the lengths of all sides and demonstrates this with examples for each shape. The video also details how to find the area of these shapes, using the base times height formula for parallelograms and the half times x times y formula for rhombuses and kites. Each section provides step-by-step instructions and examples to ensure understanding.

What is the perimeter of a shape?

• The distance around a two-dimensional shape

• The sum of all angles in a shape

• The amount of space inside a three-dimensional shape

• The length of the longest side of a shape

How do you calculate the perimeter of a parallelogram?

• Add the base and height

• Multiply the base by the height

• Add up all the sides

• Multiply all sides together

If a parallelogram has sides of 4m and 10m, what is its perimeter?

• 40 meters

• 14 meters

• 20 meters

• 28 meters

What is the perimeter of a kite with sides 5.8 cm and 6.2 cm?

• 20 cm

• 12 cm

• 18 cm

What is the formula for the area of a parallelogram?

• Base plus height

• Half base times height

• Length times width

• Base times height

How do you identify the height in a parallelogram?

• It is the perpendicular distance between two parallel sides

• It is the diagonal of the parallelogram

• It is the sum of all sides

• It is the longest side of the parallelogram

Calculate the area of a parallelogram with a base of 10m and height of 12m.

• 60 square meters

• 100 square meters

• 22 square meters

What is the formula for the area of a rhombus or kite?

• 1/2 times the product of the diagonals

• Base times height

• Length times width

• Sum of all sides

If the diagonals of a rhombus are 5 cm and 8.5 cm, what is its area?

• 21.25 square cm

• 42.5 square cm

• 17 square cm

• 13.5 square cm

For a kite with diagonals 4 cm and 5 cm, what is the area?

• 15 square cm

• 20 square cm

• 10 square cm

• 25 square cm
