15 hm²+78daa²-400m²=......are² yg bisa jawab dikasi 10 poin

15 hm(2) = 15 x 100 = 1500 are
78 daa = 78 x 10 = 780 are
400m(2) = 400 : 100 = 4 are
= 1500 + 780 = 2280 - 4 = 2276 are

1 are = 1 dam2 = 100 m2
1 ha (hektar) = 1 hektometer
1 ha = 100 are = 10.000 m2
1 ca = 1 m2
1 km2=100 ha
15 hm²+78daa - 400m² = ...... are
15 x 100 = 1500 are
78 x 10 = 780 are
400 : 100 = 4 are
1500 are + 780 are - 4 are = 2276 are

semoga membantu dan harap periksa lagi jawaban saya
