Answer:
50sqrt(231)
Step-by-step explanation:
It will be twice the area of triangle created by 40,50,20 triangle.
to find the area use herons formula
\sqrt{s(s - a)(s - b)(s - c)}
s(s−a)(s−b)(s−c)
S=(a+b+c)/2
Answer : s=(40+50+20)/2 = 55
Ar of triangle = sqrt(55x15x5x35)=25sqrt(231)
Ar of parallelogram = 50sqrt (231)
