L1 = l = 9 cm + 5 cm = 14 cm - 4 cm = 10 cm = p x l = 4 cm x 10 cm = 40 cm^2 L2 = p = 12 cm - 2 cm(dari panjang b.datar 3) = 10 cm l= 9 cm + 5 cm = 14 cm = p x l = 10 cm x 14 cm = 140 cm^2 L3 = p = 16 cm - 14 cm = 2 cm = p x l = 5 cm x 2 cm = 10 cm^2 luas gabungan = L1 + L2 + L3 = 40 cm^2 + 140 cm^2 + 10 cm^2 = 190 cm^2
= p x l
= 4 cm x 10 cm = 40 cm^2
L2 = p = 12 cm - 2 cm(dari panjang b.datar 3) = 10 cm
l= 9 cm + 5 cm = 14 cm
= p x l
= 10 cm x 14 cm = 140 cm^2
L3 = p = 16 cm - 14 cm = 2 cm
= p x l
= 5 cm x 2 cm = 10 cm^2
luas gabungan = L1 + L2 + L3
= 40 cm^2 + 140 cm^2 + 10 cm^2
= 190 cm^2
