Answer:
Step-by-step explanation:
Let x is the length of the square side.
We know: the two figures have the same area
<=> 
= π
(r being radius)
<=> x = 
r
perimeter square = 4x = 4*r*
perimeter circle = 2*r*π
<=> 390 = 4*r* + 2*r*π
<=> r = 29.16
=> perimeter square = 4*29.16*π
=> perimeter circle = 58.32π
Answer:
Step-by-step explanation:
we know that
The area of the figure is equal to the area of rectangle (figure 1) plus the area of trapezoid (figure 2)
see the attached figure to better understand the problem
The area of the rectangle is
The area of the trapezoid is
