Answer 2

Step-by-step explanation:

Original area=20*15=300 cm^2

Original area=20*15=300 cm^2New length =20+(20/100*20)=24 cm

Original area=20*15=300 cm^2New length =20+(20/100*20)=24 cmNew breadth=15+(20/100*15)=18 cm

Original area=20*15=300 cm^2New length =20+(20/100*20)=24 cmNew breadth=15+(20/100*15)=18 cmNew area=24*18=432 cm^2

Original area=20*15=300 cm^2New length =20+(20/100*20)=24 cmNew breadth=15+(20/100*15)=18 cmNew area=24*18=432 cm^2Increase in area=432–300=132

Original area=20*15=300 cm^2New length =20+(20/100*20)=24 cmNew breadth=15+(20/100*15)=18 cmNew area=24*18=432 cm^2Increase in area=432–300=132Increased % in area=132/300*100=44%
