Draw a circle, then take and draw lines across it for however many you want. circles have infinite lines of symmetry so anything works.
If we assume the given segments are those from the vertices to the point of intersection of the diagonals, it seems one diagonal (SW) is 20 yards long and the other (TR) is 44 yards long. The area (A) of the kite is half the product of the diagonals:
... A = (1/2)·SW·TR = (1/2)·(20 yd)·(44 yd)
... A = 440 yd²
Given:
The equation is

To find:
The value of b.
Solution:
We have,

Subtracting both sides by
, we get




Therefore, the value of b is
.
