Question

B) 90 feet
C) 105 feet
D) 120 feet

Answer 1

Jessie will need 157.5 feet of baby gate to enclose the baby area on all four sides.

Step-by-step explanation:

To find the dimensions of the baby area, we need to multiply the dimensions of the living room by the scale factor of 3/4. The length of the baby area will be 45 feet * 3/4 = 33.75 feet, and the width will be 60 feet * 3/4 = 45 feet.

To find the amount of baby gate needed to enclose the baby area on all four sides, we need to add up the lengths of all four sides. The total length of baby gate needed is 2 * (33.75 feet + 45 feet) = 2 * 78.75 feet = 157.5 feet. Therefore, Jessie will need 157.5 feet of baby gate to enclose the baby area on all four sides.
