Area of Triangles

Front

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

Back

Area = 1/2 × base × height

Front

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

Back

Area = 1/2 × 10 cm × 5 cm = 25 cm²

Front

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

Back

Area = 1/2 × 8 m × 3 m = 12 m²

Front

What does 'base' refer to in a triangle?

Back

The base is any side of the triangle, often the one at the bottom when drawn.

Front

What does 'height' refer to in a triangle?

Back

The height is the perpendicular distance from the base to the opposite vertex.

Front

How do you find the height of a triangle if you know the area and base?

Back

Height = (Area × 2) / base

Front

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

Back

Area = 1/2 × 6 units × 4 units = 12 units²

Front

If the area of a triangle is 30 cm² and the base is 10 cm, what is the height?

Back

Height = (30 cm² × 2) / 10 cm = 6 cm

Front

What is the area of a triangle with a base of 12 cm and a height of 5 cm?

Back

Area = 1/2 × 12 cm × 5 cm = 30 cm²

Front

What is the relationship between the base and height in calculating the area of a triangle?

Back

The area is directly proportional to both the base and height.
