Dear Student,

Total area of the wall = 25 m2Area covered by blue colour = 25×25 = 10 m2Area of the wall left = 25-10m2 = 15 m2Area covered by Red colour = 23×15 = 10 m2Area of the wall left = 15-10m2 = 5m2Hence, Area of the wall Red coloured =10 m2, Area of the wall Blue coloured =10 m2, Area of the wall Orange coloured =5 m2Fraction of wall coloured by Red=1025=25Fraction of wall coloured by Orange=525=15
