You have to multiply the two dimensions to get the area. In this case the answer will be 36 square inches.
27.713 square inches.
Each side would be 3 inches long and there are 4 sides, so 12 inches.
Multiply the lengths of two sides of the square. If a square is 5 inches tall and 5 inches long, the area of the square us 25 Inches Squared.
If the sides of a square are five inches in length, all you have to do is multiply 5 x 5 to get the number of square inches.
The area of rectangle is : 15.0
A square with a side length of 3 inches has an area of 9 square inches.
A square with a perimeter of 40 inches has sides 10 inches long which will give it an area of 100 inches2
27.713 square inches.
4.5 square inches
Each side would be 5" long, A = SideA x SideB 5 x 5 = 25
root 12 = 3.4641016151377545870548926830117
25x25=625
3 inches, because the square root of nine is three
Each side would be 3 inches long and there are 4 sides, so 12 inches.
A = s2 Area of the square = s times s
6 x 6 = 36 square inches
To find the area of a square you must times/multiply the numbers for 2 sides. Example: If you have a square that is 4 inches long and 4 inches wide, the area would be 16 inches.
