1.Decompose and Rearrange

Front

What is the area of a rectangle?

Back

The area of a rectangle is calculated by multiplying its length by its width. Formula: Area = Length × Width.

Front

How do you find the area of a composite shape?

Back

To find the area of a composite shape, decompose it into simpler shapes (like rectangles and triangles), calculate the area of each shape, and then sum them up.

Front

What does it mean to decompose a shape?

Back

To decompose a shape means to break it down into smaller, simpler shapes to make it easier to calculate the area or other properties.

Front

What is the formula for the area of a triangle?

Back

The area of a triangle is calculated using the formula: Area = 1/2 × Base × Height.

Front

What is the perimeter of a shape?

Back

The perimeter is the total distance around the outside of a shape, calculated by adding the lengths of all its sides.

Front

If two shapes have the same area, what can we say about them?

Back

If two shapes have the same area, they occupy the same amount of space, even if their shapes are different.

Front

What is a quadrilateral?

Back

A quadrilateral is a polygon with four sides and four angles.

Front

How can rearranging shapes help in finding area?

Back

Rearranging shapes can help visualize how to decompose them into known shapes, making it easier to calculate the total area.

Front

What is the area of a square?

Back

The area of a square is calculated by squaring the length of one of its sides. Formula: Area = Side × Side.

Front

What is the relationship between area and units?

Back

Area is measured in square units, such as square centimeters (cm²) or square meters (m²), indicating the two-dimensional space occupied.
