It depends on the shape of your room.
If your room is a rectangle then your perimeter is 102 feet.
Perimeter = 2*(L +W) = 2*(30 + 25) = 2*55 = 110 feet Painted surface = Perimeter*Height = 110*8 = 880 sq feet

They can, but not necessarily. Let's say we have a rectangle of 5x6 and another of 1x30. The areas of both are 30 square feet, but their perimeters are different. Perimeter of 5x6: 5+5+6+6=22 feet Perimeter of 1x30: 1+1+30+30=62 feet There are many more examples of this.
Type your answer here... Perimeter = 25+25+30+30 = 110 feet
270 feet.
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.
The perimeter is 30 feet for this rectangle.
Perimeter = 2*(L +W) = 2*(30 + 25) = 2*55 = 110 feet Painted surface = Perimeter*Height = 110*8 = 880 sq feet
It is 5 feet because 2*(10+5) = 30 feet which is the perimeter
30 * pi ≈ 94

0.5*apothegm*perimeter = 0.5*3*20 = 30 sq feet
