Area, Perimeter, and Volume Practice Test

A homeowner designs a rectangular garden that is 18 feet long and 12 feet wide, and plans to install fencing around the entire edge. The garden will be filled with soil to a uniform depth of 0.5 feet for planting. All measurements are in feet, and fencing covers only the perimeter. How much fencing is needed to enclose the garden?​

A rectangular room is 16 feet long and 13 feet wide, with walls 8 feet high. A designer plans to place trim along the floor edges and order carpet for the floor. All measurements are in feet, and the room is a perfect rectangle when viewed from above. Perimeter determines trim length, and area determines carpet needed. Determine the perimeter of the rectangle based on the provided dimensions.​
