Soal

Rani membeli sebidang tanah persegi panjang yg memiliki panjang 40m dan lebarnya 20m.berapa keliling tanah tersebut?

Pembahasan

Diketahui:

Panjang tanah persegi panjang = 40 m
Lebar tanah persegi panjang = 20 m

Ditanyakan: Keliling tanah persegi panjang

Langkah-langkah perhitungan:

Keliling tanah persegi panjang = 2 x (panjang + lebar)
Keliling tanah persegi panjang = 2 x (40 + 20)
Keliling tanah persegi panjang = 2 x 60
Keliling tanah persegi panjang = 120

Jadi, keliling tanah persegi panjang tersebut adalah 120 meter.
