Area of Shapes

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 * base * height

Front

What is the formula for the area of a rectangle?

Back

Area = length * width

Front

What is the formula for the area of a square?

Back

Area = side^2

Front

What is the formula for the area of a trapezoid?

Back

Area = 1/2 * (base1 + base2) * height

Front

What is the area of a circle?

Back

Area = π * radius^2

Front

If a triangle has a base of 10 units and a height of 5 units, what is its area?

Back

Area = 1/2 * 10 * 5 = 25 units^2

Front

If a rectangle has a length of 8 units and a width of 4 units, what is its area?

Back

Area = 8 * 4 = 32 units^2

Front

If a square has a side length of 6 units, what is its area?

Back

Area = 6^2 = 36 units^2

Front

If a trapezoid has bases of 5 units and 7 units, and a height of 4 units, what is its area?

Back

Area = 1/2 * (5 + 7) * 4 = 24 units^2

Front

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

Back

Area = π * 3^2 ≈ 28.27 units^2
