Area of Triangles and Trapezoids

Front

What is the area formula for a trapezoid?

Back

Area = (1/2) × (Base1 + Base2) × Height

Front

How do you find the area of a trapezoid with bases 6 m and 4 m, and height 3 m?

Back

Area = (1/2) × (6 + 4) × 3 = 15 m²

Front

What is the area formula for a triangle?

Back

Area = (1/2) × Base × Height

Front

How do you find the area of a triangle with base 8 cm and height 5 cm?

Back

Area = (1/2) × 8 × 5 = 20 cm²

Front

What is the area of a trapezoid with bases 10 m and 6 m, and height 4 m?

Back

Area = (1/2) × (10 + 6) × 4 = 32 m²

Front

If a triangle has a base of 12 in and a height of 7 in, what is its area?

Back

Area = (1/2) × 12 × 7 = 42 in²

Front

What is the significance of the height in calculating the area of triangles and trapezoids?

Back

The height is the perpendicular distance from the base to the top, crucial for accurate area calculation.
