The perimeter of the square is 40 inches
That is not a square, it is a rectangle and it has a perimeter of 36 inches.
4*2.5 = a perimeter of 10 inches
A square with a perimeter of 40 inches has sides 10 inches long which will give it an area of 100 inches2
It is: 30*30 = 900 square inches
If you mean 10 inch per side, then the area = 10 x 10 = 100 square inches and the perimeter will be 4 x 10 = 40 inches.
The perimeter is 40 inches.
The perimeter is 52 inches.
If the perimeter of a square is 28 inches the area is: 49 square inches.
A simple example would be a square that is ten inches by ten inches. To find the area multiply the length by the width, 10 x 10 = 100in2 (or 100 square inches). To find the perimeter of the square, 10 + 10 + 10 + 10 = 40 inches (or 10 x 4 = 40 inches).
Approximately 10 inches.
Area of square: 324 square inches Perimeter of square: 72 inches
A square has 4 sides of equal length; the perimeter of a square is 4 times the length of the side: 4 x 10 in = 40 in
