The length of a rectangle is 4 meters less than three times its width. Its area is 615 square meters. What are the dimensions of

Anarel [89]

Area= length*width

width=W

W*(3W-4)=615
3W^2-4W=615
3W^2-4W-615=0
W=41
W=-45
But W cant be a negative number so it is 41m (width)
The length is (41*3)-4=119m (length)
