Answer: 120 meters
Explanation:
The first greenhouse has a width of 10 meters, and a length of 20 meters. Since a scale factor of 2 is used, we have to multiply the length and width by 2.
Length of second greenhouse = 20 × 2 = 40
Width of second greenhouse = 10 × 2 = 20
The perimeter of the second greenhouse will then be:
= 2(length + width)
= 2(40 + 20)
= 2 × 60
= 120 meters
