Question

Hitunglah luas yang diarsir

Answer 1

Luas persegi panjang = 8 x 6 = 48 cm²

L1 = L2 = 1 x 3 / 2 = 1,5

L3 = L4 = 3 x 5 / 2 = 7,5

L yg diarsir = 48 - (L1+L2+L3+L4) => 48 - (1,5+1.5+7.5+7.5) => 48 - 18 = 30cm²
^^

Answer 2

I dan II) 1x(8-5):2= 1x3:2= 1,5
III dan IV) 3x5 :2 = 7,5
luas = 8x6 = 48
luas yg diarsir= 48-1,5-1,5-7,5-7,5
= 30
