Explanation: The best way to understand measurement is by looking at some examples. Take turns and read each example for easy understanding.

Examples:

Calculate the area of a rhombus having diagonals equal to 7 cm and 9 cm.

Step 1a

To calculate the area of a rhombus, you can use the formula:

Area = \$ (""diagonal1"" * ""diagonal2"") / 2 \$

Given that the diagonals of the rhombus are 7 cm and 9 cm, the area can be calculated as:

Area = \$ (7 cm * 9 cm) / 2 \$

Area = \$ 63 cm^2 / 2 \$

Area = \$ 31.5 cm^2 \$

Explanation: Therefore, the area of the rhombus is 31.5 square centimeters.
