Question

Berapa luas bangun diatas

Answer 1

Luas Jajargenjang (yang atas) = alas x tinggi
=(12+6)x10cm = 18x10cm = 180cm²
Luas Segitiga(yang bawah) = alas x tinggi /2
=18x8/2 = 72cm²
Luas Total = 180 cm² + 72 cm² = 252cm²

Answer 2

Luas1 = alas x tinggi
= 12+6 x 10
=180

Luas2= alas x tinggi
= {(12+6) x 8} : 2
= 144 : 2
= 72

luas keseluruhan = L1 + L2
=180 + 72
=252
