Answer 1

Answer:

Step-by-step explanation: width increased by 3 means 5+3=8

2(8+10)

2(18)=36

Perimeter of rectangle =36cm

Answer 2

perimeter of original rectangle=2(l+b)
=2(10+5)
=2(15)
=30
perimeter of new rectangle when breath is increased by 3=2(l+b)
=2(10+5+3)
=2(18)
=36
difference Between them=36-30=6cm
