Question

plzz help Mee... Tomarrow is my exam... plzz.. answer... me...

Answer 1

mid point of A(0,-1) B(2,1) is 0+2)/2,-1+1)/2 = 1,0

mid point of B(2,1) C(0,3) is 2+0)/2,1+3)/2 = 1,2

mid point of C(0,3) A(0,-1) is 0,1

So G=(1,0) F(1,2) E(0,1)

GF = √0 +4 = 2

FE = √1+1 =√2

GE = √1+1 =√2

semi perimeter = 2+2√2)/2 = 1+√2

area = √s(S-GF)(S-FE)(S-GE)
=√(1+√2)(-1+√2)

√2-1 =1
