tolong bantu ya









Hitunglah luas dan keliling bangun berikut!​

Answer 1

Jawab:

a. L = p x l

      = 17 x 8

      = 136

   K = 2p + 2l

      = (2 x 17) + (2 x 8)

      = 34 + 16

      = 50

b. L = a x t

      = 9 x 15

      = 135

   K = 2 x (a + b)

      = 2 x 24

      = 48

c. L  = 1/2 x ( A + B ) x t

      = 1/2 x 30 x 30

      = 450

   K = AB + BC + CD + AD

      = 12 + 10 + 18 + 8

      = 48

d. L = 1/2 x d1 x d2

      = 1/2 x 24 x 10

      = 120

   K = 4 x s

      = 4 x 13

      = 52

semoga membantu, maaf klo salah
