Finding Area of Shapes

Front

What is the formula to find the area of a triangle?

Back

Area = 1/2 × base × height

Front

If the base of a triangle is 10 cm and the height is 5 cm, what is the area?

Back

Area = 1/2 × 10 cm × 5 cm = 25 cm²

Front

What is the area of a rectangle with a length of 8 cm and a width of 4 cm?

Back

Area = length × width = 8 cm × 4 cm = 32 cm²

Front

How do you find the area of a square?

Back

Area = side × side

Front

If one side of a square is 6 m, what is its area?

Back

Area = 6 m × 6 m = 36 m²

Front

What is the formula for the area of a parallelogram?

Back

Area = base × height

Front

If the base of a parallelogram is 12 cm and the height is 3 cm, what is the area?

Back

Area = 12 cm × 3 cm = 36 cm²

Front

What is the area of a trapezoid?

Back

Area = 1/2 × (base1 + base2) × height

Front

If a trapezoid has bases of 10 cm and 6 cm, and a height of 4 cm, what is its area?

Back

Area = 1/2 × (10 cm + 6 cm) × 4 cm = 32 cm²

Front

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

Back

Area = π × radius² ≈ 28.27 cm² (using π ≈ 3.14)
