Area of Triangles

Front

What is the formula to calculate 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 units are used to measure area?

Back

Square units (e.g., cm², m², ft², yd²) are used to measure area.

Front

What is the area of a triangle with a base of 8 in and a height of 3 in?

Back

Area = 1/2 × 8 in × 3 in = 12 in²

Front

How does changing the height of a triangle affect its area?

Back

Increasing the height increases the area, while decreasing the height decreases the area.

Front

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

Back

Area = 1/2 × 6 m × 4 m = 12 m²

Front

If a triangle has an area of 30 ft² and a base of 10 ft, what is the height?

Back

Height = (Area × 2) / base = (30 ft² × 2) / 10 ft = 6 ft.

Front

What is the area of a triangle with a base of 15 yd and a height of 8 yd?

Back

Area = 1/2 × 15 yd × 8 yd = 60 yd²

Front

If the area of a triangle is 50 cm² and the height is 5 cm, what is the base?

Back

Base = (Area × 2) / height = (50 cm² × 2) / 5 cm = 20 cm.

Front

What is the area of a triangle with a base of 12 ft and a height of 10 ft?

Back

Area = 1/2 × 12 ft × 10 ft = 60 ft²
