Answer:
Original dimension = 46cm by 20cm
Step-by-step explanation:
From the first sentence; L - 2W = 6---------1
from second sentence; (2)(L+9+W+5) = 160 = 2L +2W = 132--------2
Substitute L = 6 + 2W from eqn 1 into eqn 2
2(6+2W) + 2W = 132
6W = 120
W = 20
L = 6 + 2(20) = 46
Original dimension = 46cm by 20cm
