Length =10
breadth=5
area A=10×5
= 50

new length = 10 + ((20/100) × 10)
= 10 + 2
= 12
new breadth= 5 + ((20/100)×5)=5+ 1
=6
new area A'=12×6
=72
percentage increase = ((A' - A)/A) ×100
= ((72 - 50)/50) × 100
= 12 × 2
= 24%

Length = 10 after increase length =(120÷100)×10=12 breadth=5after increase breadth =(120÷100)×5=6 original area =l×b =5×10=50cm sq. new area = l×b =6×12=72 area increase = ((72-50)÷50)×100=44%
