Question

find the area of parallelelogram whose two adjacent sides are 50cm and 40 cm and also find diaganal ​

Answer 1

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)
