The original area is 10 inch^2. If the area is enlarged by 120%, what is the new area?
Please help. Thanks.
Ten multiplied by 1.20
No, the answer is 14.4
Nope!
bobpursley is right,
a 120% increase of 10 inches^2 is 12 inches^2
Perhaps you stated the question incorrectly.
If the original square was 10 by 10 and the SIDE was increased to 12 then the new area would be 144
But that is not what you said.
30m-15m-20m

A 4 by 6 photo is enlarged to 150% of it's original size, what would be its new length and width?
864
To find the new area after an enlargement of 120%, you can follow these steps:
1. Calculate the increase amount by multiplying the original area by the enlargement percentage. In this case, the original area is 10 inch^2 and the enlargement percentage is 120%.
Increase amount = Original area * Enlargement percentage
Increase amount = 10 inch^2 * 120% = 10 inch^2 * 1.20
2. Add the increase amount to the original area to get the new area.
New area = Original area + Increase amount
New area = 10 inch^2 + 10 inch^2 * 1.20
Now let's do the calculations:
Increase amount = 10 inch^2 * 1.20 = 12 inch^2
New area = 10 inch^2 + 12 inch^2 = 22 inch^2
So, the new area after an enlargement of 120% is 22 inch^2.
