To find the area of the postcard after resizing the photo, we first need to calculate the new width of the photo when it is resized to 15 centimeters in length.
Original width: 6 centimeters
Original length: 4 centimeters
Resized length: 15 centimeters
We can set up a proportion to find the new width:
6 cm / 4 cm = x cm / 15 cm
6/4 = x/15
1.5 = x/15
x = 1.5 * 15
x = 22.5 cm
So, the new width of the photo after resizing will be 22.5 centimeters.
Now, we can calculate the area of the postcard by multiplying the new width and length:
Area = width * length
Area = 22.5 cm * 15 cm
Area = 337.5 square centimeters
Therefore, the area of the postcard will be 337.5 square centimeters.
