Finding the Area and Perimeter of Shapes

What is the formula for the area of a rectangle?

• Area = length × width

• Area = length + width

• Area = 2 × (length + width)

• Area = length ÷ width

What is the formula for the perimeter of a square?

• Perimeter = 4 × side

• Perimeter = 2 × (length + width)

• Perimeter = side × side

• Perimeter = 4 × (length + width)

How does changing the side length of a square affect its area?

• Increasing the side length increases the area exponentially, as area = side².

• Changing the side length has no effect on the area.

• Decreasing the side length increases the area.

• The area decreases linearly with the side length.

What is the formula for the perimeter of a rectangle?

• Perimeter = length × width

• Perimeter = 2 × (length + width)

• Perimeter = 2 × (length - width)

• Perimeter = length + width

If a square has a side length of 6 ft, what is its area?

• 24 ft²

• 30 ft²

• 36 ft²

• 42 ft²

What is the formula for the area of a triangle?

• Area = base × height

• Area = (base × height) / 2

• Area = base + height

• Area = (base + height) / 2

What is the formula for the perimeter of a triangle?

• Perimeter = side1 + side2 + side3

• Perimeter = 2 * (side1 + side2)

• Perimeter = side1 * side2 * side3

• Perimeter = side1 - side2 - side3

What is the formula for the area of a square?

• Area = side²

• Area = 2 × side

• Area = side + side

• Area = side³

What units are used to measure area?

• square feet (ft²)

• cubic feet (ft³)

• linear feet (ft)

• gallons (gal)

If a square has a side length of 4 ft, what is its area?

• 12 ft²

• 14 ft²

• 16 ft²

• 20 ft²
