tolong jawab yyaaaaa Makasih

Penyelesaian :
Luas segitiga 1
= 1/2 × 15 × 20
= 150 cm2

Luas segitiga 2
= 1/2 × 12 × 16
= 96 cm2

2 × ( Luas segitiga 1 + Luas segitiga 2 )
= 2 × ( 150 cm + 96 cm )
= 492 cm2

Sisa kawat
= 500 - 492
= 8 cm

L1
= ½ × 20 × 15
= 150 cm²

L2
= ½ × 16 × 12
= 96 cm²

2 × ( L1 + L2 )
= 2 × ( 150 + 96 )
= 492

sisa
= 500 - 492
= 8
