Question

Sebuah persegi panjang sisinya 3 2/6 cm. Berapa luas dan kelilingnya?​

Answer 1

panjang sisi = 3 2/6 = 20/6

luas = s . s

=20/6 . 20/6

= 400/36

=200/18

=100/9

=11 1/9cm²

k= 4 . s

=4 . 20/6

=80/6

=40/3

=13 1/3

Answer 2

Pembahasan:

Panjang sisi

= 3 2/6

= 20/6

Luas Persegi Panjang

= sisi × sisi

= 20/6 × 20/6

= 400/36

= 11 4/36

= 11 1/9

Keliling Persegi Panjang

= 4 × sisi

= 4 × 20/6

= 80/6

= 13 2/6

= 13 1/3
