Answer 1

21% will be the answer

Answer 2

Answer:

21%

Step-by-step explanation:

For finding the increment we use formula,

Increment $= x + y + \frac{xy}{100}$

Since length is increased by 10%

and also width is increased by 10%

So total increment is:

Increment $= 10 + 10 + \frac{10\times10}{100}$

Increment = 10 + 10 + 1 = 21%
