The width of a certain painting is 5cm less than twice the length. The length of the diagonal distance across the painting is 107cm. Find the length and width. Round your answer to 2 decimal places.

Can you check is my substitute is correct?

digonal distance: 107

width: 2L-5

length: L

a^2 + b^2 = c^2

(2L-5)^2 + L^2 = 107^2

please help and thank you
