First, we need to determine the width of the postcard in order to calculate the area.
Since the original photo is 6 cm by 4 cm, the ratio of the length to width is 6:4, which simplifies to 3:2.
If the length of the postcard is 15 cm, we can determine the width by dividing by 3 and multiplying by 2:
Width of postcard = 15 cm / 3 * 2 = 10 cm
Now, we can calculate the area of the postcard:
Area = Length * Width = 15 cm * 10 cm = 150 square centimeters
Therefore, the correct answer is:
C. 150 square centimeters
