Answer:
D
Step-by-step explanation:
Remember that the formula for the area of a rectangle is:

Where l is the our length and w is our width.
If we increase our length by 20%, this means that we add 20% or 0.2 of our old length to our old length. So, our new length will be:

Combine like terms:

Similarly, if we increase our width by 10%, this means that we add 10% or 0.1 of our old width to our old width. So, our new width is:

Combine like terms:

Therefore, our new area will be:

Substitute 1.2l and 1.1w. This yields:

Multiply:

Our old area is:

So, our area increased by a factor of 1.32.
This is the same as 32% of our old area.
So, our answer is D.
And we're done!
The circumference of the blue circle is about: 20 cm
The circumference of the orange circle is about: 10 cm
Y × 3 = 3 / 5
y = 3 / 5×3
y = 3/15
y = 1/5
In short, Your Answer would be 1/5
