perimeter of current rectangle 2(l+b)
2(30+20)=100
length increase 10% = 30+10%=33
breadth increase 5%=20+5%=21
perimeter after increasing 2(l+b)
2(33+21)=104
total increasing is 104-100=4
increasing percentage = total increasing/current perimeter ×100
4/100×100=4
hence 4% is answer.

Answer:
8% increase in perimeter
Step-by-step explanation:
Original perimeter is 20+20+30+30 = 100
Length is 30 cm
Width is 20 cm
10% of 30 is 3
5% of 20 is 1
30+3=33
20+1=21
33+33+21+21 = 66+42 = 108
8 is 8% of 100, which was the original perimeter.
So, there is an 8% increase in perimeter.
