76.4%
Step-by-step explanation:
Total area of flag:
LW = (37)(28) = 1036
Total area of red:
LW = (12 + 21)(12 + 12) = (33)(24) = 792
Percent of red:
792/1036 * 100% = 76.4%
→(37×28) unit²=1036unit²
Area of the red colour of the flag:→[{2×(12×12)}+{2×(21×12)}]
=[{2×144}+{2×252}]
=[288+504]=792unit²
Percentage of the flag is covered in red color:→(792/1036)×100=0.7645×100=76.45%
76.45% is the right answer.
