SO Area formula is
AREA = length × width
A = L× W
For length:
1cm\0.5m  = 22cm/?m    We don`t know about the meter.
if we cross multiply the answer will be 11m.
For width:
1cm\0.5m = 14cm\?m       We don`t know about the meter.
if we cross multiply the answer will be 7m.
The square meter should be 77
Because 11 × 7  = 77
