Luas persegi panjang = 48 cm Panjang = 8 cm Hitung 1/2 keliling nya!

L = p × l
48 = 8 × l
6 cm = l

1/2K = 1/2 × ( 2p + 2l)
1/2K = 1/2 × (16+ 12)
1/2K = 1/2 × 28
1/2K = 14 cm

Luas=48cm
48=Panjang×Lebar
48=8cm×Lebar
48/8=Lebar
6=Lebar

keliling = 2×(P+L)
=2×(8+6)
=2×(14)
=28cm

1/2 keliling = 28/2= 14cm
