Answer:
The length ot rectangle is 3 units.
Step-by-step explanation:
The formula for perimeter is P = 2l + 2w and the area is A = l×w. Assuming that the perimeter and area have the same values so you have to compare it :
[tex]perimeter = 2l + 2w[/tex]
[tex]area= l \times w[/tex]
[tex]perimeter = area[/tex]
[tex]2l + 2w = lw[/tex]
[tex]let \: w = 6[/tex]
[tex]2l + 2(6) = 6l[/tex]
[tex]2l + 12 = 6l[/tex]
[tex]12 = 6l - 2l[/tex]
[tex]4l = 12[/tex]
[tex]l = 3 \: units[/tex]
