+128474 Draw a parallel segment to the base from the upper right vertex to the left side of the figure
The height of the right triangle formed = sqrt (25^2 - 24^2 )= sqrt ( 625 - 576)= sqrt ( 49( = 7
So...the length of the left side of the figure = 13 + 7 = 20
So the perimeter= 20 + 25 + 13 + 24 = 82
