let the length of rectangle be 100
let the breadth of rectangle be 100
both sides are increased by 22%
Now l = 122 , b = 122
Now ,$$area\ of\ rec\tan gle=l\times\ b$$
=>14884
Area before increase = $$100\times\ 100=10000$$
percentage increased is
$$\frac{\left(14884-10000\right)}{100}=\frac{4884}{100}$$
= 48.84%
Hence option A is correct.
