Persegi Panjang PQRS alas PQ = 15 cm, Tinggi PS=20 cm. Tentukan keliling PQRS!

Jawaban yang benar adalah 70 cm.

Perhatikan konsep berikut.
keliling persegi panjang = 2(panjang x lebar)

Luas PRQS yaitu:
keliling PQRS = 2(PQ + PS)
keliling PQRS = 2(15 + 20)
keliling PQRS = 2(35)
keliling PQRS = 70 cm

Jadi keliling PQRS adalah 70 cm.
