Calculate Triangle Areas with Visuals

Front

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

Back

Area = 1/2 × base × height

Front

What is the formula to calculate the area of a parallelogram?

Back

Area = base × height

Front

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

Back

25 cm²

Front

A parallelogram has a base of 8 m and a height of 3 m. What is its area?

Back

24 m²

Front

What is the area of a triangle with a base of 12 cm and a height of 4 cm?

Back

24 cm²

Front

If the base of a triangle is doubled, how does that affect the area?

Back

The area doubles.

Front

What happens to the area of a triangle if the height is halved?

Back

The area is halved.

Front

A triangle has an area of 30 cm² and a base of 10 cm. What is its height?

Back

Height = 6 cm (Area = 1/2 × base × height) => 30 = 1/2 × 10 × height.

Front

What is the area of a parallelogram with a base of 15 in and a height of 10 in?

Back

150 in²

Front

If a parallelogram has an area of 60 cm² and a height of 5 cm, what is the length of the base?

Back

Base = 12 cm (Area = base × height) => 60 = base × 5.
