w = 4

L = 7

Step-by-step explanation:

L = length of rectangle

w = width of rectangle

L = 3 + w

A = 28

A = L*w

=(3+w) * w

28 = 3w + w^2

w^2 + 3w - 28 = 0

w^2 + 7w - 4w - 28 = 0

w ( w + 7 ) - 4 ( w + 7 ) =0

( w - 4 ) ( w + 7 ) = 0

w = 4. and w = -7

take the postive value, w = 4

therefore L= 3+4 = 7
