You need more information for an exact solution. As stated, there are an infinite number of solutions. For example, 6+6+4+4 or 7+7+3+3 or 8+8+2+2. Typically information is given about the relationship of the long and short sides in order to solve for the lengths of the sides. Since there are two unknowns, you need to have two sets of information (or equations) to solve.
Perimeter = 20+8+20+8 = 56 cm.....
The dimensions of the rectangle are 5 cm by 4 cm
Normally, the amount of the side of the rectangle below the quarter circle on it would expected to be calculated. However, the radius of the circle equals the amount that is subtracted, but in calculating the perimeter it has to be added back in again as it forms part of the perimeter. Thus the perimeter is the perimeter of the rectangle plus a quarter of the circumference of the circle. → perimeter = 2 × (20cm + 2 cm) + ¼ × 2 × π × 11 cm ≈ 44 cm + 3.14 × 11/2 = 61.27 cm.
Unlike a square, knowing the perimeter of a trapezoid is not enough to be able to calculate its area. Think of a rectangle with a perimeter of 20cm. One possibility is that it has a length of 8cm and a width of 2cm. This would give and area of 16cm2. However the rectangle could have also had a length of 7cm and a width of 3cm as this would also give a perimeter of 20cm. However this rectangle now has an area of 21cm2. To be able to calculate the area of the trapezoid, you would need to know more about it than just its perimeter.
That depends on the dimensions !... A 1 x 18 rectangle has a perimeter of 38 ! A 2 x 9 rectangle has a perimeter of 22 ! A 3 x 6 rectangle has a perimeter of 18 !
If you are talking about a rectangle, then it is 90 cm.
20cm
Perimeter = 20+8+20+8 = 56 cm.....
The dimensions of the rectangle are 5 cm by 4 cm
The perimeter of a rectangle is calculated by adding up the lengths of all four sides. In this case, the rectangle has two sides of length 6cm and two sides of length 4cm. Therefore, the perimeter would be 6cm + 6cm + 4cm + 4cm = 20cm.

what is the perimeter of the parallelogram 20cm 30cm 17cm=100
Example: To find the perimeter of a rectangular box, with length as 6cm and Breadth as 4 cm, we need to use the formula, Perimeter of a Rectangle = 2 (L+B) = 2 ( 6 cm + 4 cm) = 2 × 10 cm = 20cm.
what is the perimeter of the rectangle
4 x 5cm = 20cm
