5meters by 2 meters. how many square inches does the photograph contain

It is better to first convert the meters into inches.

Since 1 meter = 39.37 inches, we have that:

5 meters * 39.37 = 196.85 inches
2 meters * 39.37 = 78.74 inches

Therefore, 5 meters by 2 meters = 196.85 inches * 78.74 inches = 15,499.97 or roughly 15,500 square inches

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
