Question

step by step solution. only the 1 and 3 question

Answer 1

1) to find the area for such problems. there is a formula(heron's formula)

Area = root [S(S-A)(S-B)(S-C)]
$area = \sqrt{235(235 - 150)(235 - 120)(235 - 200)}$
>>>>>>>
{Where S=(A+B+C)/2 (A,B,C are sides of the triangle}

[ S =470/2=235 ]
solve it you get the answer
