area = l x w

w = area : l

w = 5.612 x 10¹⁴ : 9.2 x 10⁷

w = 6.1 x 10⁶

the perimeter: 2(l+w)

= 2(9.2 x 10⁷ + 6.1 x 10⁶)

=1.84 x 10⁸ + 1.22 x 10⁷

=10⁷(18.4+1.22)

= 1.962 x 10⁸ cm

Answer:

P = 2.0 × 10⁸ cm

Step-by-step explanation:

5.612 × 10¹⁴ = 9.2 × 10⁷ · x

6.1 × 10⁶ = x
9.2 × 10⁷ + 9.2 × 10⁷ + 6.1 × 10⁶ + 6.1 × 10⁶ = 1.962 × 10⁸ cm
