Answer 1

Answer:

1

250 m

For A POR,

I (PQ) =a= 170 m

I(QR) = b = 250 m

1 (PR) =C= 260 m

Semiperimeter (s) =

a+b+c

2

170 + 250 + 260

2

680

2

= 340 m.

AA POR)

= 5(s – a) (s – b) (s —c)

340 (340 – 170) (340 – 250) (340 - 260)

340 x 170 x 90 x 80

170 x 2 x 170 x 9 x 10 x 80

170 x 170 x 9 x 2 x 10 x 8 x 10

170 x 170 x 9 x 16 x 10 x 10

1702 x 32 x 42 x 102

= 170 x 3 x 4 x 10

= 20400 sqm

For APSR,

I(PS) = a1 = 240 m

1(SR)=b1 = 100 m

I (PR)=C1 = 260 m

Semiperimeter ()=9,+b+ci

2

240 + 100 + 260

2

= 300 m
