Area and Perimeter

What is the formula to calculate the area of a rectangle?

• Area = Length / Width

• Area = Length x Width

• Area = Length + Width

• Area = 2 x (Length + Width)

If a square has a side length of 5 cm, what is its perimeter?

• 20 cm

• 10 cm

• 15 cm

• 25 cm

What is the formula to find the perimeter of a square?

• Perimeter = side length + side length

• Perimeter = 4 * side length

• Perimeter = 2 * side length

• Perimeter = side length * side length

If a rectangle has a length of 8 cm and a width of 4 cm, what is its area?

• 32 square cm

• 16 square cm

• 12 square cm
