The image you uploaded contains a problem in Indonesian asking to determine the moments of inertia (Ixx and Iyy) and the centroid for several shapes. The given information includes that the areas of the surfaces are equal to 100 m², and there is a ratio of b:a = 5:3 for certain problems.

To start solving, I will need to go over each of the shapes (a square, circle, ellipse, etc.), calculating their respective moments of inertia (Ixx and Iyy) and centroids.

Let's begin with step-by-step calculations for each of the figures. Would you like to proceed with this approach and break down each shape?

Jika luas permukaan dari keenam bidang berikut sama dengan 100 m², tentukanlah Ixx, Iyy, c masing-masing bidang. (untuk soal c,d, dan f berlaku perbandingan nilai a : b = 5 : 3)

Learn how to calculate the moments of inertia (Ixx, Iyy) and centroids for different shapes including squares, circles, triangles, and ellipses. This problem involves a geometrical approach and utilizes key formulas and theorems to solve for areas and moments of inertia. Suitable for students in advanced high school or undergraduate engineering courses.
