Answer:

Perimeter = 70 inches

Explanation:

Length = 3k

Width = 2k

Area - lw

294 = (3k) * 2k

294 = 6k^2

Divide by 6

294/6 = 6k^2 / 6

49= k^2

Take the square root on each side

sqrt(49) = sqrt(k^2)

We only need the positive square root since length must be positive

7 =k

Length =3k =3(7) = 21 inches

Width = 2k =2(7) = 14 inches

We need the perimeter

P = 2(l+w)

P = 2(21+14)

= 2(35)

= 70 inches
