To find the area of the postcard after resizing the photo, we need to calculate the width of the photo after resizing.
Since the width of the original photo is 6 centimeters and the length is 4 centimeters, the original aspect ratio is 6:4, or 1.5:1.
If we want to resize the photo to a length of 15 centimeters while maintaining the aspect ratio, we can calculate the width as follows:
Width after resizing = (15 cm) / 1.5 = 10 cm
Now we can calculate the area of the postcard:
Area = Width * Length
Area = 10 cm * 15 cm
Area = 150 square centimeters
Therefore, the area of the postcard will be 150 square centimeters.
The correct answer is:
• 150 square centimeters
