Question

Ok, so I've got this math homework and it's a bit confusing. Can you please help?

A 9.5m length of timber is used to make a rectangular frame who's dimensions are in the ratio of 3:2. Find the length and width of the frame.

Please don't answer, just explain how! Thanks

Answer 1

if x and y are taken as length and width,
x:y=3:2, x/y=3/2,x=3y/2
2(x+y)=9.5
2(3y/2+y)=9.5
5y=9.5
y=1.9
x=2.85

Answer 2

rectangle is made by a length of 9.5, which is the perimeter
