A trapezoid is given: c = 4.2 cm, h = 8 cm, S = 42.4 cm, d = 8.4
It would help if you calculated the following: sides a and b, and perimeter o:

Correct answer:

a =  6.4 cm
b =  8.0082 cm
o =  27.0082 cm

Step-by-step explanation:

c=4.2 v=8 S=42.4 d=8.4 a=2 S/vc=2 42.4/84.2=6.4 cm
x=d2v2=8.42822.5612 y=acx= b=v2+y2=82+(0.3612)2=8.0082 cm
o=a+b+c+d=27.0082 cm
