Answer:

Step-by-step explanation:

We know that area of rectangle is length × width, while the perimeter is 2 (length + width ) okay

We don't know the width but we can make subject formula of width from area, so width = Area ÷ length

Otherside we can say that perimeter = 2 [L+(A÷L)]

= 2 [7.4 × 10^6 + (4.44 × 10^13 ÷ 7.4 × 10^6)]

= 2 [7.4 × 10^6 + 0.6 × 10^7 ]

= 2 [ 7,400,000 + 6,000,000]

= 2 [13,400,000]

= 26,800,000 when we write that in scientific notation it will be

= 2.68 × 10^7
