Drawing on paper or chalkboard is easier than using the compose-field in the algebra dot com system,
but MAKE THE DRAWING. You have a rectangle garden of 7 meters by 12 meters. Extend the 7 meters
by x meters in both directions; and extend the 12 meters also by x in both directions. This gives
you an outer rectangle and the uniform width of the border, the region between the two rectangles,
is x IN BOTH directions. The outer dimensions of the extended garden with the border are
(7+2x) and (12+2x).

Does your border area have 92 square meters?

Area of border AND garden,
Area of just garden without border,
Area of JUST the border,

Simplify and solve for x.
