Bantu jawab hari ini dikumpul.​

Jawaban:

8. K= 4xS

= 400/4= S

= 100 cm= S

L= SxS

= 100x100

= 10.000 cm2

9. K= 4xS

= 4x12

= 48 cm2

10. L= SxS

= 3.600= SxS

= 60 cm= S

K= 4xS

= 4x60

= 240 cm

Jawaban :

8.) keliling = 400

4s = 400

s = 100 cm

luas = s²

= 100²

= 10.000 cm²

= 1 m²

9.) keliling = 4s

= 4 × 12

= 48 cm

10.) luas = 3.600

s² = 3.600

s = √3.600

s = 60 cm

keliling = 4s

= 4 × 60

= 240 cm

semoga membantu:)
