A.)√10²-8² = √36 = 6 cm sisi bawah = 6+6+6 = 18 cm K = 10+10+6+18 = 44 cm L = 1/2 (6+18) x 8 = 12 x 8 = 96 cm² B.) K = 10+8+8+14 = 40 cm L = 1/2(8+14) x 8 = 11 x 8 = 88 cm²

boleh tanya? itu sisi bawah 6+6+6 darimana?
sisi bawah = 6+6+6 = 18 cm
K = 10+10+6+18 = 44 cm
L = 1/2 (6+18) x 8
= 12 x 8 = 96 cm²
B.) K = 10+8+8+14 = 40 cm
L = 1/2(8+14) x 8
= 11 x 8 = 88 cm²
