How do you find the area of a composite figure?

Back

To find the area of a composite figure, divide it into simpler shapes, calculate the area of each shape, and then sum those areas.

What is the formula for the area of a rectangle?

Back

Area = length × width.

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 × base × height.

How do you find the perimeter of a composite figure?

Back

To find the perimeter, add the lengths of all the outer sides of the figure.

Front

What is the perimeter of a rectangle?

Back

Perimeter = 2 × (length + width).

Front

What is the perimeter of a triangle?

Back

Perimeter = side1 + side2 + side3.

Front

What is the significance of units in area calculations?

Back

Units in area calculations are squared (e.g., cm², m²) because area measures two-dimensional space.

Front

What is the difference between area and perimeter?

Back

Area measures the space inside a shape, while perimeter measures the distance around a shape.
