Saw 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 a length of 15 cm. What will be the area of the postcard

Answer 1

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

Given that the original photo measure 6 cm x 4 cm, we can calculate the ratio of the length and width as follows:

6 cm / 4 cm = 1.5

Therefore, the width of the postcard after resizing will be:

15 cm / 1.5 = 10 cm

Now, we can calculate the area of the postcard by multiplying the length and width:

Area = Length x Width
Area = 15 cm x 10 cm
Area = 150 cm²

Therefore, the area of the postcard will be 150 cm².
