We look for the dimensions of the first rectangle:
For the length:
(2/6) L = 180
L = (6/2) * (180)
L = 540
For the width:
(3/5) W = 90
W = (5/3) * (90)
W = 150
We look for the dimensions of the new rectangle:
For the length:
L '= 540-150
L '= 390
For the width:
W '= (1/3) * (390)
W '= 130
Answer:
The dimensions of the new rectangle are:
L '= 390
W '= 130
