Area of 2D Shapes

Front

What is the formula for the area of a rectangle?

Back

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

Front

What is the formula for the area of a triangle?

Back

The area of a triangle is calculated using the formula: A = \frac{1}{2} \times base \times height.

Front

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

Back

The area of a square is calculated using the formula: A = side × side. Therefore, A = 5 cm × 5 cm = 25 cm².

Front

How do you find the area of a circle?

Back

The area of a circle is calculated using the formula: A = \pi \times radius^2.

Front

What is the area of a rectangle with a length of 10 m and a width of 4 m?

Back

A = length × width = 10 m × 4 m = 40 m².

Front

What is the area of a triangle with a base of 6 cm and a height of 4 cm?

Back

A = \frac{1}{2} \times base \times height = \frac{1}{2} \times 6 cm \times 4 cm = 12 cm².

Front

What is the area of a shape with a length of 8 ft and a width of 3 ft?

Back

A = length × width = 8 ft × 3 ft = 24 ft².

Front

What is the area of a square with a side length of 7 in?

Back

A = side × side = 7 in × 7 in = 49 in².

Front

What is the area of a circle with a radius of 3 cm?

Back

A = \pi \times radius^2 = \pi \times (3 cm)^2 = 9\pi cm².

Front

What is the area of a rectangle with a length of 12 cm and a width of 5 cm?

Back

A = length × width = 12 cm × 5 cm = 60 cm².
