Area of Triangles and Find Missing Height or Base

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 does the height of a triangle represent?

Back

The height is the perpendicular distance from the base to the opposite vertex.

Front

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

Back

Area = 1/2 × 8 m × 6 m = 24 m²

Front

If a triangle has an area of 30 cm² and a base of 10 cm, what is the height?

Back

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

Front

What is the height of a triangle if the area is 48 in² and the base is 12 in?

Back

Height = (Area × 2) / base = (48 in² × 2) / 12 in = 8 in

Front

Which part of the triangle is the base?

Back

The base is any one of the sides of the triangle, typically the bottom side.

Front

What is the area of a triangle with a base of 15 ft and a height of 4 ft?

Back

Area = 1/2 × 15 ft × 4 ft = 30 ft²

Front

If the area of a triangle is 50 cm² and the height is 5 cm, what is the base?

Back

Base = (Area × 2) / height = (50 cm² × 2) / 5 cm = 20 cm

Front

What is the area of a triangle with a base of 9 m and a height of 3 m?

Back

Area = 1/2 × 9 m × 3 m = 13.5 m²
