Area of Triangles

Front

What is the formula to find the area of a triangle?

Back

Area = (Base x Height) / 2

Front

If a triangle has a base of 10 cm and a height of 5 cm, what is its area?

Back

Area = (10 cm x 5 cm) / 2 = 25 cm²

Front

Back

Area is the amount of space inside a shape, measured in square units.

Front

How do you calculate the area of a triangle with a base of 8 m and a height of 3 m?

Back

Area = (8 m x 3 m) / 2 = 12 m²

Front

What is the area of a triangle with a base of 4 in and a height of 6 in?

Back

Area = (4 in x 6 in) / 2 = 12 in²

Front

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

Back

Height = (Area x 2) / Base = (30 cm² x 2) / 10 cm = 6 cm

Front

What units are used to measure area?

Back

Square units, such as cm², m², in², ft².

Front

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

Back

Area = (12 ft x 10 ft) / 2 = 60 ft²

Front

If a triangle has an area of 18 m² and a height of 3 m, what is the base?

Back

Base = (Area x 2) / Height = (18 m² x 2) / 3 m = 12 m

Front

What is the area of a triangle with a base of 5 yd and a height of 8 yd?

Back

Area = (5 yd x 8 yd) / 2 = 20 yd²
