Answer:
Length & Breadth could be : 4 meters , 5 meters
Step-by-step explanation:
Border, ie perimeter measurement of Rectangle = 2 ( Length + Breadth )
So, 2 (Length + Breadth) = 18
Length + Breadth = 18 / 2
Length + Breadth = 9
So, sum of length & breadth must be = 9.
(L, B) = (2,5) ; (2,8) ; (2,9) and (3,5) ; (3,8) ; (3,9) don't satisfy this condition. (4,5) ; (4,8) also don't.
(L, B) = (4,5) satisfy it. As sum 4 + 5 = 9.
