What is mean by Rectangle?
A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
Given that;
A polygon is shown in figure.
Now, We get;
The polygon is made by two rectangles.
Hence, The area of the polygon is,
⇒ 17 x 5 + 11 x 5
⇒ 85 + 55
⇒ 140 units²
Thus, The area of the polygon is,
⇒ 140 units²

87 + 32 = 119 degrees
180 -119 = 61 degrees
Angle C = 61 degrees
Now we can easily find angle 1 when we know that angles on one side of a straight line will always add up to 180 degrees. Since angle C is 61 degrees then angle 1 is...
180 - 61 = 119 degrees

The shortest perimeter for a fixed area is when you use
the area to make a circle.
The next shortest perimeter for a fixed area is when you
use the area to make a square.
But the longer and skinnier you make it, the longer the perimeter
becomes, without any limit.
Examples:
circle, radius = 3.523 . . area = 39 . perimeter = 22.14
√39 by √39 . . . . . area = 39 . . . . . perimeter = 24.98
6 by 6.5 . . . . . . . area = 39 . . . . . perimeter = 25
5 by 7.8 .. . . . . . . area = 39 . . . . . perimeter = 25.6
4 by 9.75 . .. . . . . area = 39 . . . . . perimeter = 27.5
3 by 13 . . . . . . . . area = 39 . . . . . perimeter = 32
2 by 19.5 . .. . . . . area = 39 . . . . . perimeter = 43
1 by 39 . . . . . . . . area = 39 . . . . . perimeter = 80
0.1 by 390 . . . . . area = 39 . . . . . perimeter = 780.2
0.01 by 3,900 . . area = 39 . . . . . perimeter = 7,800.02
y=width
area=xy
xy=39 ⇒x=39/y
Perimeter of a rectangle=2x+2y
P(x,y)=2x+2y
P(y)=2(39/y)+2y
P(y)=78/y+2y
P(y)=(78+2y²)/y
Therefore ;P(y) will be gratest if y⇒0
We calculate the next limit.
lim y⇒0 (78+2y²)/y=lim y⇒0 (78/y+2y)=∞
For exmple:
y=0.1 ft
then;; x=39/ 0.1=390 ft
P(2*390 ft+2*0.1 ft)=780.2
y=0.001 ft
Then; x=39/0.001=39000 ft
P(2*39000 ft+0.001 ft)=78000,002 ft.
Answer: the greatest perimeter of a rectangle with an area of 39 ft²⇒∞
