Tolong dijawab yaa :) nomor 2 dan 3 :))!

2. L¹ = p × l
= 16 × 11
= 176 cm²

L² = ½ × a × t
= ½ × 2 × 11
= ½ × 22
= 11 cm²

L.Gabungan = 176 + 11 = 187 cm²

3.L.Lingkaran = π × r²
= 22/7 × 35²
= 22/7 × 1.225
= 3.850 cm²



Semoga Membantu :) Maaf kalo salah

2. L1 = p x l = 16x11 = 176 cm (persegi panjang)
L2 = 1/2 x a x t = 1/2 x 2 x 11 = 11 cm (segitiga)
Maka, luas bangun adalah
L1+L2 = 176 + 11 = 187 cm^2

3. Diameter/garis tengah = 70 cm
Jari-jari = 70/2 = 35 cm
L lingkaran = π.r^2 = 22/7 x 35 x 35
= 110x35
= 3.850 cm^2
