Rectangular field

One dimension of the rectangular field is 56 m greater than second dimension. If each side of the rectangle increases by 10 m, increases the surface field is 1480 m2 . Determine dimencions of the field.

Correct result:

a =  41 m
b =  97 m

Solution:

x=y+56 (x+10)(y+10)xy=1480  x=41 y=97
