The correct answer is B.
Explanation:
In a flat squared surface such as the one of a shed, the area is calculated by multiplying two sides. In this case, the side is 4 meters long, and therefore the formula to calculate the area is A (area) = side x side
A = 4 meters x 4 meters
A= (4 x 4) (m x m)
A= 16
This means the correct answer is B because this shows the correct number of meters in the area (16) and using square meters or is the correct unit to express the area or measurement of a surface.
