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

Answer 1

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.

Answer 2

no

Answer 3

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.
