IS trapezoid

Calculate the length of diagonal u and height v of isosceles trapezoid ABCD, whose bases have lengths a = |AB| = 37 cm, c = |CD| = 29 cm and legs b = d = |BC| = |AD| = 28 cm.

Correct result:

v =  27.7 cm
u=|AC|=|BD| =  43.1 cm

Solution:

a=37 cm c=29 cm r=28 cm x=(ac)/2=(3729)/2=4 cm v=r2x2=28242=16 3=27.7 cm
u=v2+(ax)2=27.71282+(374)2=1857=43.1 cm
