10*2+5*2 = 30 CM
The perimeter would be 5x2+6x2=10+12=22cm
Well, well, well, aren't we getting fancy with our math questions? If the area of a rectangle is 45cm2, and you want to find the perimeter, you need more information. The length and width are required to calculate the perimeter, so without those dimensions, I'm afraid I can't give you a straight answer.

To find the area of a rectangle, you multiply its length by its width. Given the area of 20 cm², we need to find two numbers that multiply to 20. The possible dimensions are 4 cm by 5 cm or 2 cm by 10 cm. To find the perimeter of a rectangle, you add up all its sides. With a perimeter of 18 cm, the possible dimensions are 4 cm by 5 cm, as 4 + 5 + 4 + 5 = 18 cm.
It is not. The perimeter of a 1 cm square is 4 cm. The perimeter of a 5 km * 15 km rectangle is 4000000 cm: a million times as large!
The dimensions of the rectangle are 5 cm by 4 cm
Perimeter = sum of the lengths of sides = 5* 7 cm = 35 cm
40 cm Perimeter = 2 L + 2W = 30 + 10
If it's a 12 by 5 rectangle then the perimeter is: 12+5+12+5 = 34 cm
To find the perimeter of a regular pentagon with 9cm sides, you would multiply the length of one side by the total number of sides. In this case, 9cm x 5 sides = 45cm. Therefore, the perimeter of a regular pentagon with 9cm sides is 45cm.
10*2+5*2 = 30 CM
Oh, what a happy little rectangle we have here! To find the perimeter, you simply add up all the sides. So, for this rectangle with sides of 9cm and 5cm, the perimeter would be 2(9cm) + 2(5cm) = 18cm + 10cm = 28cm. Just a few simple brushstrokes and you've got your answer!
If the shape measuring 8 centimeters by 5 centimeters is a rectangle, the perimeter of the rectangle is 25 centimeters (2w + 2l)
The perimeter would be 5x2+6x2=10+12=22cm
To draw a shape with a 9cm perimeter, you can create a triangle, square, or rectangle. For a triangle, you could have sides measuring 3cm, 3cm, and 3cm. For a square, all four sides would be 2.25cm. For a rectangle, two sides could be 2cm and the other two sides could be 2.5cm. These shapes will all have a perimeter of 9cm.
