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 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 3 cm?

Back

Area = 1/2 × 8 × 3 = 12 cm²

Front

A triangle has a base of 12 m and a height of 4 m. What is its area?

Back

Area = 1/2 × 12 × 4 = 24 m²

Front

What is the area of a triangle with a base of 6 inches and a height of 10 inches?

Back

Area = 1/2 × 6 × 10 = 30 inches²

Front

If the area of a triangle is 20 m² and the base is 5 m, what is the height?

Back

Height = (Area × 2) / base = (20 × 2) / 5 = 8 m

Front

What is the area of a triangle with a base of 15 cm and a height of 10 cm?

Back

Area = 1/2 × 15 × 10 = 75 cm²

Front

A triangle has an area of 18 units² and a base of 6 units. What is the height?

Back

Height = (Area × 2) / base = (18 × 2) / 6 = 6 units

Front

What is the area of a triangle with a base of 9 m and a height of 4 m?

Back

Area = 1/2 × 9 × 4 = 18 m²

Front

If a triangle has a height of 7 mm and an area of 21 mm², what is the base?

Back

Base = (Area × 2) / height = (21 × 2) / 7 = 6 mm
