Area of Parallelograms and Triangles

Front

What is the formula for the area of a parallelogram?

Back

The area of a parallelogram is calculated using the formula: Area = base × height.

Front

How do you find the area of a triangle?

Back

The area of a triangle is calculated using the formula: Area = (base × height) / 2.

Front

If the area of a rectangle is 72 square units and one side is 9 units, how do you find the other side?

Back

To find the other side, divide the area by the known side: Other side = Area / known side = 72 / 9 = 8 units.

Front

What is the area of a rectangle with a length of 10 units and a width of 5 units?

Back

Area = length × width = 10 × 5 = 50 square units.

Front

What is the relationship between the base and height of a triangle when calculating its area?

Back

The base and height must be perpendicular to each other to accurately calculate the area of the triangle.

Front

How do you calculate the area of a rectangle?

Back

The area of a rectangle is calculated using the formula: Area = length × width.

Front

What is the area of a parallelogram with a base of 8 ft and a height of 6 ft?

Back

Area = base × height = 8 ft × 6 ft = 48 square feet.

Front

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

Back

Area = (base × height) / 2 = (10 m × 5 m) / 2 = 25 square meters.

Front

What is the area of a piece of paper that measures 10 inches by 9 inches?

Back

Area = length × width = 10 in × 9 in = 90 square inches.

Front

What is the significance of units when calculating area?

Back

Units must be consistent when calculating area; the result will be in square units (e.g., square feet, square meters).
