Dik: Panjang sisi persegi 28 cm
Dit: Luas bangun datar tsb???
Jawaban:
Luas persegi:
L= sisi × sisi
L= 28 × 28
L= 784 cm²
Luas ½ lingkaran:
d=28 cm >> r=14 cm
L=½πr²
L=½ × 22/7 × 14 × 14
L=22 × 14
L= 308 cm²
Luas total bangun tsb adalah:
LPersegi + L½Lingkaran =
784 + 3081 = 1.092 cm²
So luas bangun datar tsb adalah 1.092 cm²

Penjelasan dengan langkah-langkah:
L = (28×28) + (1/2×1/4×22/7×28×28)
L = 784 + (1/1×1/1×22×2×7)
L = 784 + 308
L = 1.092 cm²
