Question

Tolong jawab ya kakak dan dijelaskan secara perinci ya​

Answer 1

Titik Berat

• persegi panjang 1

A1 = 2 × (8 - 2) = 12

titik berat 1 = (1,5)

• persegi 2

A2 = 2 × 2

titik berat 2 = (1,1)

• persegi panjang 3

A3 = 4 × 2 = 8

titik berat 3 = (4,1)

Titik berat benda

x = (A1x1 + A2x2 + A3x3)/(A1 + A2 + A3)

x = (12.1 + 4.1 + 8.4)/(12 + 4 + 8)

x = 48/24

x = 2

y = (A1y1 + A2y2 + A3y3)/(A1 + A2 + A3)

y = (12.5 + 4.1 + 8.1) / 24

y = 72/24

y = 3

titik berat benda = (x,y) = (2,3) ✔
