Back

The area of a rectangle is calculated using the formula: Area = length × width.

Front

What is the formula for the area of a triangle?

Back

The area of a triangle is calculated using the formula: Area = (base × height) / 2.

Front

What is the formula for the area of a circle?

Back

The area of a circle is calculated using the formula: Area = π × radius².

Front

If the radius of a circle is 5 cm, what is its area?

What is the area of a square with a side length of 10 units?

Back

Area = side × side = 10 units × 10 units = 100 units².

Front

If a square has an area of 64 units², what is the length of one side?

Back

Length of one side = √(64 units²) = 8 units.
