To find the perimeter of the outside seating area, we need to add up the lengths of all the sides.
Side AB:
√((-3 - (-11))^2 + (11 - 11)^2) = √8^2 = 8 feet
Side BC:
√((-3 - (-3))^2 + (1 - 11)^2) = √10^2 = 10 feet
Side CD:
√((-11 - (-3))^2 + (1 - 1)^2) = √8^2 = 8 feet
Side DA:
√((-11 - (-11))^2 + (1 - 11)^2) = √10^2 = 10 feet
Adding up the lengths of all the sides:
8 + 10 + 8 + 10 = 36 feet
Therefore, the restaurant will need 36 feet of wall material to build the new outside seating area.
The correct answer is: 36 feet
A restaurant is building an outside seating area. The owner created a map with the coordinates A(−11,11) , B(−3,11) , C(−3,1) , and D(−11,1) . Each unit on the coordinate plane represents 1 foot. Solve to find out how many feet of wall material they will need to build the new area (the perimeter).(1 point)
