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?
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.
