Arectangle is 3x feet long and 4 feet wide. the value of the pertimeter (in feet) is equal to the value of the area (in square feet). find x.

x= 2,4,6,8any even number

Step-by-step explanation:

Perimeter is 4+4 + 3x+3x = 8+6x

The result of 8 + 6 times a number  should be a multiple of 4.

PERIMETER                                                           AREA

8+(6*2)= 8+ 12 =                                                      4*5=20

8+(6*4)  = 8 +24=32                                                 4*8=32

8+(6*6) =8+36 =44                                                    4*11=44

8+(6*8)=8+48=56                                                      4*14=56

And so on
