$luas : trapsium = frac{1}{2} frac{alas : atas : + alas : bawah}{2} times t \ luas : trapesium = frac{1}{2} times frac{5 + 27}{2} times 9 \ luas : trapesium = frac{1}{2} times frac{32}{2} times 9 = frac{32}{4} times 9 = 8 times 9 = 72 : {cm}^{2}$

4) L = a×t = 23×11 = 253 cm²
5) L = 1/2×t×(a+b) = 1/2×9×(5+27) = 1/2×9×32 = 9×16 = 144 cm²

semoga membantu
