Final answer:
The surface area of a rectangle with dimensions s = 4 meters and l = 5 meters is 20 square meters (m²), assuming the figure is rectangular.
Step-by-step explanation:
To find the surface area of the figure with given dimensions of s = 4 meters and l = 5 meters, we first need to consider the shape of the figure. However, since the type of the figure is not mentioned in the question, let's assume it is a rectangle. The surface area of a rectangle is given by the formula Area = length × width. Using the provided dimensions, we calculate the area as follows:
Area = s × l = 4 m × 5 m = 20 m².
Thus, the surface area of the figure is 20 square meters (m²) when s = 4 meters and l = 5 meters. This result is already expressed in square meters and adheres to the correct number of significant figures, which in this case is two because '4' and '5' each have one significant figure.
