Area of a triangle

Front

What is the formula to find 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 is the area of a triangle with a base of 8 in and a height of 4 in?

Back

Area = 1/2 × 8 in × 4 in = 16 in²

Front

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

Back

Area = 1/2 × 12 cm × 10 cm = 60 cm²

Front

If a triangle has an area of 30 cm² and a base of 6 cm, what is the height?

Back

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

Front

What is the area of a triangle with a base of 14 cm and a height of 3 cm?

Back

Area = 1/2 × 14 cm × 3 cm = 21 cm²

Front

If the area of a triangle is 24 in² and the height is 6 in, what is the base?

Back

Base = (Area × 2) / height = (24 in² × 2) / 6 in = 8 in

Front

What is the area of a triangle with a base of 9 units and a height of 5 units?

Back

Area = 1/2 × 9 units × 5 units = 22.5 units²

Front

If a triangle has a base of 15 cm and an area of 45 cm², what is the height?

Back

Height = (Area × 2) / base = (45 cm² × 2) / 15 cm = 6 cm

Front

What is the area of a triangle with a base of 20 in and a height of 10 in?

Back

Area = 1/2 × 20 in × 10 in = 100 in²
