To resize the photo without distorting it, we need to maintain the aspect ratio.
The original aspect ratio of the photo is 6:4, which simplifies to 3:2.
To find the width of the resized photo, we can use the proportion:
4cm / 6cm = x / 15cm
Solving for x, we get:
x = (4/6) * 15
x = 10cm
Therefore, the resized photo will be 10cm by 15cm.
To find the area of the postcard, we can use the formula:
Area = length * width
Area = 15cm * 10cm
Area = 150cm^2
Therefore, the area of the postcard will be 150 cm^2.
Natalia has a photo that measures 6cm by 4cm. She wants to resize the photo into the size of a postcard with the length of 15cm. What will be the area of the postcard?
