Answer:
Third option
Step-by-step explanation:
Since there is a <em>less</em><em> </em><em>than</em><em> </em>sign, we need to have an opened circle at -12, shading everything to the left. If it were <em>less</em><em> </em><em>than</em><em> </em><em>or</em><em> </em><em>equal</em><em> </em><em>to</em>,<em> </em>then we would put a <em>closed </em><em>circle</em>.

Formula- Area = L • W
So...
Length = 18 + 3
Width = 18 + 3
Since you’re adding 18 + 3 for Length AND Width, you’re going to get a sum of 21 for each.
Length = 21
Width = 21
Now you’re gonna want to multiply 21 by itself.
21 • 21 = 21 + 420 = ?
Which leaves you with the final sum of...
Area = 441 yds.
Your answer would be 460, hope i helped youuu :)
