Area of a triangle

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 6 cm, what is the area?

Back

Area = 1/2 × 10 cm × 6 cm = 30 cm²

Front

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

Back

Area = 1/2 × 8 m × 5 m = 20 m²

Front

How do you convert the area from square centimeters to square meters?

Back

Divide the area in cm² by 10,000.

Front

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

Back

Area = 1/2 × 12 in × 4 in = 24 in²

Front

If a triangle has an area of 48 cm² and a base of 12 cm, what is the height?

Back

Height = (Area × 2) / base = (48 cm² × 2) / 12 cm = 8 cm

Front

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

Back

Area = 1/2 × 15 m × 10 m = 75 m²

Front

If the area of a triangle is 30 cm² and the height is 5 cm, what is the base?

Back

Base = (Area × 2) / height = (30 cm² × 2) / 5 cm = 12 cm

Front

What is the area of a triangle with a base of 20 cm and a height of 3 cm?

Back

Area = 1/2 × 20 cm × 3 cm = 30 cm²

Front

How can you find the area of a triangle if you only know the lengths of all three sides?

Back

Use Heron's formula: Area = √[s(s-a)(s-b)(s-c)], where s = (a+b+c)/2.
