Area of Triangles

Front

What is the formula for 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 units are used to measure area?

Back

Square units (e.g., cm², m², ft²) are used to measure area.

Front

How does changing the base or height of a triangle affect its area?

Back

Increasing the base or height increases the area; decreasing them decreases the area.

Front

What is the area of a triangle with a base of 8 m and a height of 3 m?

Back

Area = 1/2 * 8 m * 3 m = 12 m²

Front

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

Back

Area = 1/2 * 6 in * 4 in = 12 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 5 yd and a height of 8 yd?

Back

Area = 1/2 * 5 yd * 8 yd = 20 yd²

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

What happens to the area of a triangle if both the base and height are doubled?

Back

The area increases by a factor of 4.
