Area and Perimeter

Front

What is the formula for calculating the perimeter of a rectangle?

Back

Perimeter = 2 * (length + width)

Front

If a rectangle has a length of 5 cm and a width of 3 cm, what is its perimeter?

Back

Perimeter = 2 * (5 cm + 3 cm) = 16 cm

Front

What is the formula for calculating the area of a rectangle?

Back

Area = length * width

Front

If a rectangle has a length of 4 units and a width of 2 units, what is its area?

Back

Area = 4 units * 2 units = 8 square units

Front

What is the difference between perimeter and area?

Back

Perimeter is the distance around a shape, while area is the amount of space inside a shape.

Front

How do you calculate the perimeter of a triangle?

Back

Perimeter = side1 + side2 + side3

Front

If a triangle has sides of lengths 3 cm, 4 cm, and 5 cm, what is its perimeter?

Back

Perimeter = 3 cm + 4 cm + 5 cm = 12 cm

Front

What is the formula for calculating the area of a triangle?

Back

Area = 1/2 * base * height

Front

If a triangle has a base of 6 units and a height of 4 units, what is its area?

Back

Area = 1/2 * 6 units * 4 units = 12 square units

Front

What is the perimeter of a square with a side length of 5 cm?

Back

Perimeter = 4 * side length = 4 * 5 cm = 20 cm
