D). keliling = 2(10+8) = 36 cm luas = alas x tinggi = 10 x 9 = 90 cm²
E). keliling = 20 + 8 + 13 + 5 = 46 cm luas = a + b x t 2 = 20 + 13 x 5 2 = 82,5 cm²
semoga membantu

D.) K= AB + BC + CD + AD = 10 + 8 + 10 + 8 = 36 cm L= a x t = 10 x 9 = 90 cm persegi e.) K= AB + BC + CD + AD = 20 + 8 + 13 + 5 = 46 cm L= 1/2 x (20 + 13) x tinggi = 1/2 x 33 x 5 = 1/2 x 165 = 82,5 cm persegi
= 36 cm
luas = alas x tinggi
= 10 x 9
= 90 cm²
E). keliling = 20 + 8 + 13 + 5
