Area of Triangles

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 × base × height

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 units²

Front

What is the area of a triangle with a base of 8 cm and a height of 6 cm?

Back

Area = 1/2 × 8 × 6 = 24 cm²

Front

A triangle has an area of 30 cm² and a base of 10 cm. What is its height?

Back

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

Front

What is the area of a triangle with a base of 12 m and a height of 4 m?

Back

Area = 1/2 × 12 × 4 = 24 m²

Front

If the height of a triangle is doubled, how does that affect the area?

Back

The area doubles because Area = 1/2 × base × (2 × height) = 2 × (1/2 × base × height)

Front

What is the area of a triangle with a base of 14 mm and a height of 8 mm?

Back

Area = 1/2 × 14 × 8 = 56 mm²

Front

A triangle has a base of 9 inches and an area of 27 inches². What is its height?

Back

Height = (Area × 2) / base = (27 × 2) / 9 = 6 inches

Front

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

Back

Area = 1/2 × 5 × 10 = 25 m²

Front

If a triangle has an area of 40 cm² and a height of 5 cm, what is the base?

Back

Base = (Area × 2) / height = (40 × 2) / 5 = 16 cm
