Front

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

Back

Area = side × side = 4 cm × 4 cm = 16 cm²

If a square has a side length of 6 cm, what is its perimeter?

Back

Perimeter = 4 × side = 4 × 6 cm = 24 cm

Front

What is the area of a triangle with a base of 10 cm and a height of 5 cm?

Back

Area = 1/2 × base × height = 1/2 × 10 cm × 5 cm = 25 cm²

Front

What is the perimeter of a triangle with sides measuring 3 cm, 4 cm, and 5 cm?

Back

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