Area of rectangle=2Length+2Width
Suppose Lenght=L
then Width=L-4
Put the values in the above equation
Area=2(L+W)
5=2(L+(L-4))
5=2(2L-4)
5=4L-8
4L=13
L=13/4
L=3.25
So Length=3.25
Width=L-4
Width=3.25-4
Width=-0.75
Suppose Lenght=L
then Width=L-4
Put the values in the above equation
Area=2(L+W)
5=2(L+(L-4))
5=2(2L-4)
5=4L-8
4L=13
L=13/4
L=3.25
So Length=3.25
Width=L-4
Width=3.25-4
Width=-0.75
