The following problem, Natalia prints, a photo of a covered bridge. The print measure 6 cm x 4 cm she wants to resize the photo into the size of a postcard with the length of 15 cm. What will be the area of the postcard will it be 60 cm² 2.5 cm² 150 cm² are 24 cm².

To find the area of the postcard, we need to first calculate the width of the postcard after resizing the photo.

The original photo measures 6 cm x 4 cm, so we need to calculate the ratio of the original length to the new length:

6 cm / 4 cm = 1.5

Now, multiply the new length of the postcard (15 cm) by this ratio to find the new width:

15 cm x 1.5 = 22.5 cm

Now, calculate the area of the postcard:

Area = length x width
Area = 15 cm x 22.5 cm
Area = 337.5 cm²

Therefore, the area of the postcard will be 337.5 cm².
