Final answer:
The area of a rectangle that is 3.2 m wide and 5.1 m long is 16.32 square meters. This calculation considers significant figures as both measurements are provided with two decimal places.
Step-by-step explanation:
The area of a rectangle is calculated by multiplying its length by its width. In this case, the rectangle is 3.2 m wide and 5.1 m long. So, the area is found by multiplying these two dimensions:
Area = Length × Width = 3.2 m × 5.1 m = 16.32 square meters.
When expressing this value, we should consider the appropriate number of significant figures. Since both measurements are given to two decimal places, our final area should be expressed to the same level of precision.
