Question

ini soal kelas 6 sd buat kakak kakak yg bisa tolong jawab yaa

Answer 1

7.) L=1/2 X d1 x d2
250 = 1/2 x 20 x d2
250 = 10 x d2
25 = d2
25 = AC

8.) L = 1/2 (a+b)t
3060 = 1/2 (70+100)t
3060 = 1/2 x170 t
3060 = 85 t
36 =t

9) L = x r²
= 22
   --- x 21 x 21
    7
= 1386 cm²

no 6, 10 kurang jelas angkanya
