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.

Result

a =  41 m
b =  97 m

Solution:

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