Select the correct number or words from the drop-down menus to complete the statements.
To count and find the area, divide the shape into smaller, measurable units and count the number of units that fit inside the shape. The area is exact if the units are consistent and the counting is accurate.
Example 1:
A square is divided into smaller squares, with each smaller square having a side length of 1 cm. By counting the number of smaller squares that fit inside the larger square, the exact area can be determined.
Example 2:
A circular rug is divided into smaller triangles, with each triangle having a base of 5 meters and a height of 3 meters. By counting the number of triangles that fit around the edge of the rug and in the center, an estimate of the area can be obtained.
