Area = 9 sq inches Length of side = sqrt(9) = 3 inches Perimeter = 4*Length of side = 4*3 = 12 inches
Each side would be 3 inches long and there are 4 sides, so 12 inches.
It is: 4*9 = 36 inches
If the area of a square is 81, then the length of a side is 9. Add up the length of all four sides to get the perimeter: 9 + 9 + 9 + 9
Each side must be 36/4 ie 9 in so area is 81 sq in
Area = 9 sq inches Length of side = sqrt(9) = 3 inches Perimeter = 4*Length of side = 4*3 = 12 inches
Each side would be 3 inches long and there are 4 sides, so 12 inches.
A square is a four sided polygon with four right angles whose sides are all congruent. This means that the area of a square is equal to the length of one side squared. So a square with an area of 81 sq. in. has a side length of 9 inches. The perimeter is the distance around the outside of a figure. For a square, this is equal to four times the side length. Here 4 * 9 = 36. So, the perimeter of this square is 36 inches.
It is: 4*9 = 36 inches
9 inches
Area of the square = 9 square inchesArea = side * side= 3 inches * 3 inches= 9 square inches
9 inches
It isn't a square. But the perimeter is 46ft
The area of square with a perimeter of 36 is 81. If the perimeter is 36, then each side must be 36 divided by 4, or 9. The area of a square is side squared, so that is 9 squared or 81.
The idea is to first calculate the length of one side. Then you can multiply that by 4 to get the perimeter.
Area of a triangle = 1/2*base*height Use Pythagoras to find the height which is 7.794228634 inches Area = 1/2*9*7.794228634 = 35.07402885 square inches Answer: 35 square inches to the nearest square inch.
Perimeter = 36. Since we're told it's a square, we know that all 4 sides are equal. So each side is (36/4) = 9 in. Then the area is S2 = 81 square inches.
