Yang debit sory ya aku rada lupa pelajaran sd.. no 2, L1 = tinggi = 20 - 5 = 15 cm\ = jumlah sisi sejajar x tinggi : 2 = 10+ 40 = 50 x 15 = 750 :2 = 375 cm² L2 = p x l = 40 x 5 = 200 cm² luas gabungan = 375 + 200 = 575 cm²
No 3. L1 = A x L = 4x8 = 32 cm² L2 = 9 + 6 = 15 x 9 = 135 cm² luas gabungan = 135 + 32 = 167 cm²
no 2,
L1 =
tinggi = 20 - 5 = 15 cm\
= jumlah sisi sejajar x tinggi : 2
= 10+ 40 = 50 x 15 = 750 :2 = 375 cm²
L2 =
p x l
= 40 x 5 = 200 cm²
luas gabungan = 375 + 200 = 575 cm²
No 3.
L1 =
A x L = 4x8 = 32 cm²
L2 =
9 + 6 = 15 x 9 = 135 cm²
luas gabungan = 135 + 32 = 167 cm²
