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
2
