6) Chapter 10 Area

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 * base * height

Front

How do you find the area of a parallelogram?

Back

Area = base * height

Front

What is the area of a triangle with a base of 10 units and a height of 5 units?

Back

Area = 1/2 * 10 * 5 = 25 units²

Front

If a triangle has an area of 30 units² and a base of 6 units, what is its height?

Back

Height = (Area * 2) / base = (30 * 2) / 6 = 10 units

Front

What is the area of a rectangle with a length of 8 cm and a width of 4 cm?

Back

Area = length * width = 8 * 4 = 32 cm²

Front

What is the area of a square with a side length of 5 cm?

Back

Area = side² = 5 * 5 = 25 cm²

Front

How do you calculate the area of a trapezoid?

Back

Area = 1/2 * (base1 + base2) * height

Front

What is the area of a circle with a radius of 3 cm?

Back

Area = π * radius² ≈ 3.14 * 3² ≈ 28.26 cm²

Front

If the area of a triangle is 40 cm² and the base is 10 cm, what is the height?

Back

Height = (Area * 2) / base = (40 * 2) / 10 = 8 cm

Front

What is the area of a parallelogram with a base of 12 cm and a height of 5 cm?

Back

Area = base * height = 12 * 5 = 60 cm²
