The area of a room is 56 square feet. The width of the room is 7 feet. If Alicia is going to put an animal wall border on all four walls of the room, how many feet of border does she need? (1 point) Responses 8 feet 15 feet 28 feet 30 feet 1 answer
To find the total length of the border, we need to find the perimeter of the room.
The perimeter of a rectangle is found by adding up all four sides. Since the opposite sides of a rectangle are equal, we can find the length of one side by dividing the total area by the width.
Area = Length x Width
56 = Length x 7
Length = 56/7 = 8 feet
The perimeter is found by adding up all four sides:
Perimeter = 2(Length + Width)
Perimeter = 2(8 + 7)
Perimeter = 30 feet
Therefore, Alicia needs 30 feet of wall border.
