Help meeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

Answer 1

Width = 5.7 ft, Length = 10.5 ft

Explanation:

Let the width be
`w`. Then, the length is
`2w-0.9`.

`w(2w-0.9)=59.85 \\ \\ 10w(20w-9)=5985 \\ \\ 200w^2-90w-5985=0 \\ \\ 40w^2-18w-1197=0 \\ \\ (4w+21)(10w-57)=0 \\ \\ w=5.7 (w>0) \\ \\ \implies 2w-0.9=2(5.7)-0.9=10.5`
