Area of a Triangle

Front

What is the formula to calculate 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 4 cm, what is the area?

Back

Area = 1/2 × 10 cm × 4 cm = 20 cm²

Front

What is the height of a triangle if the area is 24 cm² and the base is 6 cm?

Back

Height = (Area × 2) / base = (24 cm² × 2) / 6 cm = 8 cm

Front

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

Back

Area = 1/2 × 5 in × 3 in = 7.5 in²

Front

If a triangle has an area of 30 ft² and a base of 10 ft, what is the height?

Back

Height = (Area × 2) / base = (30 ft² × 2) / 10 ft = 6 ft

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

If the area of a triangle is 18 cm² and the height is 3 cm, what is the base?

Back

Base = (Area × 2) / height = (18 cm² × 2) / 3 cm = 12 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

If a triangle has a base of 7 in and an area of 21 in², what is the height?

Back

Height = (Area × 2) / base = (21 in² × 2) / 7 in = 6 in

Front

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

Back

Area = 1/2 × 15 ft × 10 ft = 75 ft²
