Yes, because a square is a rectangle. You can have a square where all four sides are 3 units, making the perimeter 12 units. You can then have a rectangle where the sides are 4 and 2 units; 4+4+2+2=12.
To draw a shape with a perimeter of 9, you can start by choosing a simple polygon, such as a triangle or a rectangle, and assigning lengths to its sides that add up to 9. For example, a triangle could have sides measuring 3, 3, and 3 units, or a rectangle could have sides measuring 2 and 5 units. Ensure that the total length of all sides equals 9 units. Once the side lengths are determined, sketch the shape accordingly.
Assuming that 7 and 9 are the lengths - in some units - of the sides of a rectangle, its perimeter is 32 units of length.
"Perimeter" means the distance around something. Just add the four sides of the rectangle.
The perimeter is the sum of its 4 sides and its area is length times width
