Materi: Geometri / Integral

Maaf perhitungan salah
Larsir = Ltrape + Lsgitiga
= (2+3)/2 × 2 + 1/2 × 3 × 3
= 5 + 9/2 = 9,5

[tex]\displaystyle \text{dibatasi sumbu }y\\x=0\\\\\text{titik potong kedua garis}\\y=y\\5-x=2x-4\\9=3x\\3=x\\\\L=\int\limits^{x_2}_{x_1}y_2-y_1\,dx\\L=\int\limits^{3}_{0}5-x-2x+4\,dx\\L=\int\limits^{3}_{0}9-3x\,dx\\L=\left9x-\frac32x^2\right|^{3}_{0}\\L=9(3-0)-\frac32(3^2-0^2)\\L=9(3)-\frac32(9)\\L=\frac{54-27}2\\L=\frac{27}2\\\boxed{\boxed{L=13,5}}[/tex]
