Tom prints a photo of a penguin. The print measures 6 cm by 4 cm. He wants to reize the photo into the size of a postcard with a length of 15 cm. What will the area be
First, we need to calculate the area of the original photo:
Area = Length x Width
Area = 6 cm x 4 cm
Area = 24 square cm
Next, we need to calculate the scale factor for resizing the photo to fit the length of the postcard:
Scale Factor = Length of Postcard / Length of Original Photo
Scale Factor = 15 cm / 4 cm
Scale Factor = 3.75
Now, we need to calculate the new width of the resized photo:
New Width = Width of Original Photo x Scale Factor
New Width = 6 cm x 3.75
New Width = 22.5 cm
Finally, we can calculate the area of the resized photo:
Area = Length x Width
Area = 15 cm x 22.5 cm
Area = 337.5 square cm
Therefore, the area of the resized photo will be 337.5 square cm.

Apologies for the mistake. Let's recalculate the area of the resized photo using the correct width.
Given:
Original photo dimensions: 6 cm x 4 cm
Resized postcard length: 15 cm
1. Calculate the scale factor:
Scale Factor = Resized Postcard Length / Original Photo Length
Scale Factor = 15 cm / 6 cm
Scale Factor = 2.5
2. Calculate the new width of the resized photo:
New Width = Original Photo Width x Scale Factor
New Width = 4 cm x 2.5
New Width = 10 cm
3. Calculate the area of the resized photo:
Area = Resized Postcard Length x New Width
Area = 15 cm x 10 cm
Area = 150 square cm
Therefore, the area of the resized photo will be 150 square cm. Thank you for your patience.
