Question

two sides of a triangular field are 85 M and 154 M respectively and it's perimeter 324 meters is 324 meters. find the area of it.​

Answer 1

Given.. two side of a triangular field is A=85m and B=154m so C=let X

perimeter of triangular field= A+B+C=324

85+154+X=324

239+X=324

so, X= 324-239=85

C=85m

now,

find the are of triangular field by using herons formula, so

semi perimeter=A+B+C/2=85+154+85/2=324/2

so Sp= 162

under root√s(s-a)(s-b)(s-c)

under root√162(162-85)(162-154)(162-85)

under root√162×77×8×77

now area =2772m
