Area of triangles

Front

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

Back

Area = 1/2 × base × height

Front

What is the area of a triangle with a base of 10 cm and a height of 5 cm?

Back

Area = 1/2 × 10 cm × 5 cm = 25 cm²

Front

If the base of a triangle is doubled, how does the area change?

Back

The area also doubles.

Front

What is the height of a triangle if its area is 30 cm² and the base is 10 cm?

Back

Height = (Area × 2) / base = (30 cm² × 2) / 10 cm = 6 cm

Front

What is the area of a triangle with a base of 8 m and a height of 4 m?

Back

Area = 1/2 × 8 m × 4 m = 16 m²

Front

What does 'base' refer to in a triangle?

Back

The base is any side of the triangle on which the height is measured.

Front

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

Back

Area = 1/2 × 12 units × 10 units = 60 units²

Front

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

Back

Height = (Area × 2) / base.

Front

What is the area of a triangle with a base of 6 cm and a height of 9 cm?

Back

Area = 1/2 × 6 cm × 9 cm = 27 cm²

Front

What is the area of a triangle with a base of 5 m and a height of 3 m?

Back

Area = 1/2 × 5 m × 3 m = 7.5 m²
