Hitunglah luas dan kelilingnya

Hitunglah luas dan kelilingnya

Jawab:

$L = (6times 6) + (15times6) = 36 + 90 = 126 m^2\\K = 6+6+6+(6+6)+(15-6)+15 = 18+12+9+15 = 20+24 = 44 m$

Tahap 1

L = (6 × 6) + (15 × 6)

L = 36 + 90

L = $boxed{orange{bf{126~m^2}}}$

Tahap 2

K = 6 × 3 + (6 + 6) + (15 – 6) + 15

K = 18 + 12 + 9 + 15

K = 30 + 9 + 15

K = 39 + 15

K = $boxed{orange{bf{54~M}}}$
