Question

See attachment.

Answer 1

W = L-8
Area = W * L = 10
(L-8)*L = 10
L^2 - 8L - 10 = 0
Solve to find L.

Answer 2

I got \[L=4+\sqrt{26},4-\sqrt{26}\]

Answer 3

It has to be the first one because the second number is negative and Length can't be negative.

Answer 4

so the answer is \[4+\sqrt{26}\]

Answer 5

Yes for length. Now find W using W = L-8.

Answer 6

how do i solve that?!

Answer 7

W = L - 8
W = 4 + SQRT(26) - 8
W = SQRT(26) - 4

Answer 8

i got 1.099019514

Answer 9

Yes.
