Let its width be w and length= w+6
2(w+6+w)=52
4w+12=52
4w=40
w=10
Area=10*(10+6)=160
I think it's -2 to -1 is the right answer maybe
but i hope it helps u !!
Answer:140ft2
Step-by-step explanation: area= base times height
Area=14ft . 10ft
Area=140ft2
-10x=-12x + 21 + 11
-10x= -12 + 32
-10x + 12x = 32
2x = 32
X = 32/2
