Hello dear user!!! ✌️✌️
Here is your answer goes like this :
============================================================
Your question...
A parallelogram has sides 30m and 14m long and one of the diagonals is 40m long find its area
Answer:
let ABCD be the given parallelogram
area of parallelogram ABCD = 2 x (area of triangle ABC)
now a = 30m, b = 14m and c = 40m
s=1/2(a+b+c)
==>s=1/2 x (30+14+40) = 42
==>Area of triangle ABC = √[s(s-a)(s-b)(s-c)]
= √[42(12)(28)(2)]
= 168sq m
area of parallelogram ABCD = 2 x 168 = 336 sq m
THERFORE THE AREA OF PARALLELOGRAM is 336 m²
The answer has been explained....
