Solve teh folllowing promblem: Natatlis prints a phto o 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?

Answer 1

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

The original photo measures 6 cm by 4 cm. To resize it proportionally, we can use the ratio of the original length to the desired length:

Original length / Original width = New length / New width

6 cm / 4 cm = 15 cm / x

Cross multiplying, we get:

6x = 60
x = 10

Therefore, the width of the resized photo will be 10 cm.

Now, we can calculate the area of the postcard:

Area = length x width
Area = 15 cm x 10 cm
Area = 150 square centimeters

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