Answer 1

Answer:

given:

perimeter of rectangle=2(sum of length and breadth)

let length be l and breadth be b

FORM EQUATION: 2(L+B)

GIVEN WIDTH IS 8 UNITS AND PERIMETER IS LESS THAN 40

= 2(l+8)= 39

= 2l+ 16=39

2l=39-16

2l= 23

l= 23/2

Answer 2

Answer:

given:

perimeter of rectangle=2(sum of length and breadth)
