The definition of 'perimeter' is the sum of the distances around a given two-dimensional object. Assuming that we are referring to a rectangular room (or at least a 4-sided room with 2 sets of parallel sides), then the answer is simply 2(30 + 40) = 140 feet.
12 feet
40 feet
A rhombus can't have two different side lengths. They all must be the same. If the sides are 30-in, then the perimeter is 120-in. If they're 40-in, then the perimeter is 160-in.

If the table is a circle and the perimeter is 40 feet, then the diameter (rounded to 2 decimal places) would be 12.74 circumference = diameter x pi so, diameter = circumference / pi

The distance around or Perimeter of a Rectangle is equal to the sum of the length of the 4 sides.18' + 40' + 18' + 40' = 116'
To find the perimeter of a rectangular pool, you can use the formula: Perimeter = 2(length + width). For a pool that is 12 feet by 8 feet, the calculation is: Perimeter = 2(12 + 8) = 2(20) = 40 feet. Therefore, the perimeter of the pool is 40 feet.
To find the total square footage of a 30x40 feet house, you multiply the length and width: 30 feet × 40 feet = 1,200 square feet. Therefore, the house has a total area of 1,200 square feet. If you were asking about the perimeter, it would be 2 × (30 + 40) = 140 feet.
40 feet
The perimeter is exactly one mile (5,280 feet).
Width: 1200/40 = 30 feet
A rhombus can't have two different side lengths. They all must be the same. If the sides are 30-in, then the perimeter is 120-in. If they're 40-in, then the perimeter is 160-in.
