Answer 1

Question: The sides of a triangular field are 325m 300m and 125.its. it's area is

Answer: it will be done by using herons formula 

s= 325  + 300 + 125 /2 = 375

( s-a) = (375 - 325 ) = 50
(s-b)  = (375 - 300 ) = 75 
(s-c)  = ( 375 - 125 ) = 250

√ s (50) (75) (250)

√ 375 x 937500

351562500

Answer 2

the answer is √351562500 =18750m square
$sides \: of \: triangular \: field \: are \\ a = 325m \\ b = 300m \\c = 125m \\ semi - perimeter = a + b \ + c \div 2 \\ = 750 \div 2 \\ = 375m \\ ar \: of \: field = \sqrt{s(s - a)(s - b)(s - c)$
