Accepted Solution
A:
Answer:x= 2,4,6,8.......any even numberStep-by-step explanation:Perimeter is 4+4 + 3x+3x = 8+6xThe result of 8 + 6 times a number should be a multiple of 4.PERIMETER AREA8+(6*2)= 8+ 12 = 4*5=208+(6*4) = 8 +24=32 4*8=328+(6*6) =8+36 =44 4*11=448+(6*8)=8+48=56 4*14=56And so on.......
