Question

A farmer is constructing a second rectangular greenhouse similar to another greenhouse using a scale factor of 2. The first greenhouse has a width of 10 meters, and a length of 20 meters. What is the perimeter of the second greenhouse.

Answer 1

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
