Heya...
Here is your answer ---
Length = 20 cm
Area = 220 cm^2
=> Area of rectangle = length × breadth
=> 220 = 20 × Breadth
=> Breadth = 220/20
=> Breadth = 11 cm
When doubled,
Length = 40 cm
Breadth = 22 cm
New Area = length × breadth
Area = 40 × 22
Area = 880 cm^2
HOPE IT HELPS....!!!!

the new area will be 880sq.cm if each of its side is doubled
first while finding area the breadth will be 11cm
by doubling length and breadth we get 40 and 22 so finding area we get 880sqcm
