1. What is the area of a rhombus?

There are two ways to find the area of a rhombus:

Multiply the base by the height


calculate half the product of the diagonals.

2. Which units are used to measure the area of a country?

Square kilometres (km2)

3. What has to be done if one measurment is in one unit and the other in a different unit?

Before multipying, both measurements must be in the same units.
e.g. If the length of a rectangle is given as 3m and the width as 75cm, one way would be to change 3m into 300cm. then the area can be found by multiplying 300 by 75 to give an area of 22 500 cm

4. Now that acres are no longer used as a unit of area, how are the areas of house sections measured?

Land areas are measured in square metres (m2) or hectares.
