Luas = 2 kali Luas Segitiga + Luas P. Panjang = 2.1/2.8.6 + 14.22 = 48 + 308 = 356 cm²

L segitiga= 2 x 1/2 x a x t = 2 x 1/2 x 6 x 8 = 48 L persegi panjang = p x l = 22 x 14 = 308 L total= Lsegitiga+Lpersegi panjang = 48 = 308 = 356
= 2.1/2.8.6 + 14.22
= 48 + 308
= 356 cm²
L persegi panjang = p x l = 22 x 14 = 308
L total= Lsegitiga+Lpersegi panjang = 48 = 308 = 356
