Answer 1

Diket
r=7cm
p=14cm
l=14cm
L=L persegi panjang+L1/2 lingkaran+L1/2lingkaran
 =(p×l )+( 1/2×π×r²) + (1/2×π×r²)
 =(14×14) + (1/2×22/7×7²) + (1/2×22/7×7²)
=(196)+(77)+(77)
 =3550cm²

Answer 2

Luas Persegi + Luas Lingkaran
= S x S + pi r kuadrat (sorry saya ngga bisa masukin gambarnya)
= 196 + 154
