___________________________________________

L Persegi = S × S

L Persegi = 28 × 28

L Persegi = 784 cm²

___________________________________________

L Segitiga = ½ × A × T

L Segitiga = ½ × 12 × 28

L Segitiga = ½ × 336

L Segitiga = 168 cm²

___________________________________________

L ½ Lingkaran = ½ × π × r²

L ½ Lingkaran = ½ × 22/7 × 14²

L ½ Lingkaran = ½ × 22/7 × 196

L ½ Lingkaran = ½ × 616

L ½ Lingkaran = 308 cm²

___________________________________________

L Gabungan

= L Persegi + L Segitiga + L ½ Lingkaran

= 784 + 168 + 308

= 784 + 476

= 1.260 cm²

Luas total

= luas persegi + luas ½lingkaran + luas segitiga

= (s × s) + (½πr²) + (½ × a × t)

= (28 × 28) + (11/7 × 14 × 14) + (½ × 12 × 28)

= 784 + (11 × 2 × 14) + (12 × 14)

= 784 + 308 + 168

= 1.260 cm²
