Teresa had a family photo with the dimensions of 12 inches by 16 1/2 inches. What is the area of the photo in square inches? Please help!!! :(
198 inches or 396/2
If the photo were 3x4 would you have any trouble finding its area?
If not, what's so different about 12 x 16.5?
To find the area of the photo, you can use the formula:
Area = Length × Width
In this case, the length of the photo is 12 inches, and the width is 16 1/2 inches. However, it would be easier to work with a uniform measurement, so we need to convert the width to a decimal or a mixed number, whichever is more convenient.
To convert the mixed number, 16 1/2, into a decimal, you can divide the numerator (1) by the denominator (2) and add it to the whole number (16):
16 + 1/2 = 16 + 0.5 = 16.5
Now we can substitute the values into the formula:
Area = 12 inches × 16.5 inches
Multiplying 12 by 16.5 gives us:
Area = 198 square inches
Therefore, the area of the photo is 198 square inches.
