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.

LaoAny number greater than or equal to 4*sqrt(45) cm or 26.83 cm (approx).
To see that, suppose L ≥ sqrt(45) cm be the length of the rectangle
and let B = 45/L cm
Then Area = L*B = L*(45/L) = 45 cm2
If L = 9cm, then B = 45/9 = 5 cm and then perimeter = 2*(L+B) = 28 cm
If L = 90 cm, then B = 0.5 cm and P = 181 cm
If L = 900 cm, then B = 0.05 cm and P = 1800.1 cm
If L = 9000000 cm then B = 0.000005 cm and P = 18000000.00001 cm
As can be seen, the perimeter can be increased without limit.

How do you find the area of a rectangle with a perimeter of 36m?
how do you find the area of a rectangle witha perimeter of 36 in You don't. You need more information For example a 1 x 17 rectangle has a perimeter of 36 and its area is 17. But a 2 x 16 rectangle also has a perimeter of 36 and its area is 32.
Can a rectangle have a greater perimeter than another one but have a greater area too?
yes it can; a rectangle 5 by 2 has perimeter 14 and area 10 for example; a rectangle 10 by 2 has perimeter 24 and area 20, both greater.
Can a rectangle have a greater perimeter and also have a greater area?
Of course, a rectangle can have a greater perimeter and a greater area. Simply double all the sides: the perimeter is doubled and the area is quadrupled - both bigger than they were.
How is perimeter and area related in a rectangle?
The perimeter of a rectangle is the distance around the rectangle. The area of a rectangle is the space inside the rectangle. To calculate either one you need the length and the width of the rectangle. To calculate the area multiply the length times the width. To calculate the perimeter add the length+width+length+width (that is the distance all the way around)
If you have an area of 100 square meters what is the perimeter?
40 meters.
