Answer:

1225 cm²

Step-by-step explanation:

Keliling persegi diberikan sebagai 4 × a

Dimana a = Panjang sisi

Keliling persegi di atas = 140

Karenanya:

4a = 140

a = 140/4

a = 35 cm

Panjang sisi bujur sangkar = 35cm

Luas persegi = (Panjang sisi) ²

Karenanya:

Luas persegi = (35cm) ²

= 1225 cm²

Luas persegi sebelum membagi adalah 1225 cm²
