Jawaban:
a. 716cm²
b. 1.362,5cm²
Penjelasan:
L. Persegi = p × l
= 24 × 28 = 672cm²
L. Lingkaran = π × r²
= 22/7 × 14²
= 22 × 2²
= 22 × 4
= 88cm²
karena cuma setengah, jadi dikali ½ = 44cm²
L. Bangun (Keseluruhan)
= 672 + 44 = 716cm²
L. Persegi = S²
= 35²
= 1225cm²
L. Lingkaran = π×r²
= 22/7 × 35²
= 22 × 5²
= 22 × 25
= 550cm²
karena cuma ¼, jadi dikali ¼ = 137,5cm²
= 1225 + 137,5 = 1362,5cm²
Maaf kalau salah
