Cannot answer - depends on measurements
Examples:
4 x 20 = 80
4 + 4 + 20 + 20 = 48
10 x 8 = 80
10 + 10 + 8 + 8 = 36
16 x 5 = 80
16 + 16 + 5 + 5 = 42

20 x 20 = 400 The room has 400 square feet on the floor, 400 square feet on the ceiling, and (80 x height of the room) square feet on the walls.
Assuming the room is 8 ft by 10 ft (the question does not say so), the area would be 8*10 = 80 square feet
It is: 40*80 = 3200 square feet

Area of square 400 so dimensions 20 x 20 making perimeter 80
400 square feet.
80 square feet. Just multiply length by width - the answer is the square footage.
To calculate the square footage, multiply the length by the breadth. So, 10 feet x 8 feet = 80 square feet
A 20-unit square has a perimeter of 80 units.

20 x 20 = 400 The room has 400 square feet on the floor, 400 square feet on the ceiling, and (80 x height of the room) square feet on the walls.
If you are looking for the square footage of the room, the height shouldn't make a difference. So the square footage would just be 10 ft x 10 ft = 100 square feet. If you are looking for surface area of all the walls, floor, and ceiling, that would be 100+100+80+80+80+80 = 520 square feet If you're looking for the cubic footage of the room, then you would use all three dimensions. 8ft x 10ft x 10ft = 800 cubic feet.
Assuming the room is 8 ft by 10 ft (the question does not say so), the area would be 8*10 = 80 square feet
In a square, if perimeter=80 meters, then side=20 meters, and area= 400 square meters.
It is: 40*80 = 3200 square feet
A square with an area of 400 square units has a perimeter of 80 units.
If a square has a perimeter of 80 meters, then each side is 20 meters in length. (80/4 sides of a square=20) The area of a square is side2, so 20*20 equals 400. The area of a square that has a perimeter of 80 meters is 400 meters2.
