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? (1 point)

Answer 1

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

Let the width of the resized photo be x cm. We know that the original photo had dimensions 6 cm by 4 cm.

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

Now that we have the width of the resized photo, we can calculate the area of the postcard:
Area = length * width
Area = 15 cm * 22.5 cm
Area = 337.5 square centimeters

Therefore, the area of the postcard will be 337.5 square centimeters.
