berapa kelilling dan luas persegi panjang jika diketahui ukuran panjang 19 cm dan lebar 14 cm?

K = 2( p + l )
= 2(19 + 14)
= 2 x 33
= 66 cm

L = p x l
= 19 x 14
= 266 cm²

Semoga Bermanfaat! {^=^}
Makasih:D

K = 2 × ( p + l )
K = 2 × ( 19cm + 14cm )
K = 2 × 33cm
K = 66cm

L = p × l
L = 19cm × 14cm
L = 266cm²
