Jawaban:
277 cm²
Penjelasan dengan langkah-langkah:
luas persegi panjang + ½ lingkaran
= [20 × 10] + ½ × [22/7 × 7 × 7]
= 200 + ½ × [22 × 7]
= 200 + ½ × 154
= 200 + 77
= 277 cm²
Luas persegi panjang:
L = p × l
L = 20 × 10
L = 200 cm²
Luas ½ lingkaran:
L = ½ × π × r²
L = ½ × 22/7 × 7²
L = ½ × 22/7 × 49
L = ½ × 22 × 7
L = 11 × 7
L = 77 cm²
Luas gabungan:
L = L persegi panjang + L ½ lingkaran
L = 200 + 77
L = 277 cm²
