A 5x7 photo us enlarged so that it's new dimensions are 10x14. How does the area of the enlarged photo compare to the area original photo?
5*7 = 35 square inches
10*14 = 140 square inches
The larger picture has 4 times the area of the smaller photo.
To find out how the area of the enlarged photo compares to the area of the original photo, we need to calculate the areas of both photos.
The area of a rectangle can be found by multiplying its length by its width.
For the original photo, the dimensions are 5x7. So, the area of the original photo is 5 * 7 = 35 square units.
For the enlarged photo, the dimensions are 10x14. So, the area of the enlarged photo is 10 * 14 = 140 square units.
Comparing the two areas, the area of the enlarged photo (140 square units) is larger than the area of the original photo (35 square units).
To compare the areas of the original photo and the enlarged photo, we need to calculate the areas of both and compare them.
The area of a rectangle can be found by multiplying its length by its width. Therefore, to find the area of the original 5x7 photo, we multiply 5 by 7:
Area of original photo = 5 x 7 = 35 square units
Similarly, for the enlarged photo with dimensions 10x14, we calculate its area by multiplying 10 by 14:
Area of enlarged photo = 10 x 14 = 140 square units
Now, to compare the two areas, we can calculate the ratio of the area of the enlarged photo to the area of the original photo:
Ratio of areas = Area of enlarged photo / Area of original photo
= 140 square units / 35 square units
= 4
Therefore, the area of the enlarged photo is four times the area of the original photo.
