Solve the following problem: Natalia prints a photo of a covered bridge. The print measures 6 centimeters by 4 centimeters. She wants to resize the photo into the size of a postcard with a length of 15 centimeters. What will be the area of the postcard?

Question

Please answer correctly.

Answer 1

We can start by finding the scale factor between the original print and the postcard.

Scale factor = postcard length / original length
Scale factor = 15 / 6
Scale factor = 2.5

This means that the postcard will be 2.5 times larger than the original print.

To find the dimensions of the resized photo, we can multiply the original dimensions by the scale factor:

Length = 6 cm x 2.5 = 15 cm
Width = 4 cm x 2.5 = 10 cm

Now that we have the dimensions of the postcard, we can find its area:

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

Therefore, the area of the postcard will be 150 square centimeters.
