Area of irregular polygons

Front

What is the formula for calculating the area of a triangle?

Back

Area = 1/2 * base * height

Front

How do you find the area of a rectangle?

Back

Area = length * width

Front

What is the formula for the area of a trapezoid?

Back

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

Front

What is the definition of an irregular polygon?

Back

An irregular polygon is a polygon that does not have all sides and angles equal.

Front

How can you calculate the area of a composite figure?

Back

Divide the figure into simpler shapes, calculate the area of each shape, and then sum the areas.

Front

What is the significance of units in area measurement?

Back

Units indicate the size of the area being measured, such as square feet (ft²) or square centimeters (cm²).

Front

What is the relationship between the side lengths and the area of a polygon?

Back

The area can depend on the lengths of the sides, especially in irregular polygons, where specific formulas may apply.

Front

How do you determine the height of a polygon when calculating area?

Back

The height is the perpendicular distance from the base to the opposite vertex.

Front

What is the area of a polygon with vertices at (0,0), (4,0), (4,3), (0,3)?

Back

Area = length * width = 4 * 3 = 12 square units.

Front

What is the formula for the area of a parallelogram?

Back

Area = base * height.
