Alright I'm not exactly sure what category this question falls under, but it was a question part of a "completing the square" unit.
A rectangle is 6m longer than wide. The diagonal is 30m. Find the dimensions of the rectangle.
I drew a diagram, L representing Length and W representing Width.
Then I subbed w=20.8m into L = W +6 to find L.
L = 26.8M
So the dimensions were 20.8m and 26.8m. For some reason this doesn't look right. No completing the square was involved in this question. Is my answer correct?
