Finding Area of Parallelograms & Triangles

Front

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

Back

A = bh, where A is the area, b is the base, and h is the height.

Front

How do you calculate the area of a triangle?

Back

A = 1/2 * b * h, where A is the area, b is the base, and h is the height.

Front

What is the area of a triangle with a base of 6 cm and a height of 12 cm?

Back

36 cm² (A = 1/2 * 6 * 12).

Front

What is the area of a parallelogram with a base of 10 in and a height of 4 in?

Back

40 in² (A = 10 * 4).

Front

What is the area of a rectangle with a base of 6 cm and a height of 18 cm?

Back

108 cm² (A = 6 * 18).

Front

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

Back

25 m² (A = 1/2 * 10 * 5).

Front

What is the area of a parallelogram with a base of 15 cm and a height of 8 cm?

Back

120 cm² (A = 15 * 8).

Front

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

Back

The area doubles, since A = 1/2 * b * h.

Front

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

Back

12 in² (A = 1/2 * 8 * 3).

Front

What is the area of a parallelogram with a base of 7 m and a height of 9 m?
