You're given that the formula for area is lw, and you're given the l and w values. So just plug them in. They have the same unit of measurement (inches) so you can just multiply.
A = lw
A = (5.5)(2.1)
A = 11.55 in²

= , substitute values
= ( cross- multiply )
10 XY = 180 ( divide both sides by 10 )
XY = 18
