L.Gabungan = ( L.Segitiga ) + ( L.¾Lingkaran )
= ( ½ × a × t ) + ( ¾ × π × r² )
= ( ½ × 14 × 14 ) + ( ¾ × 22/7 × 14² )
= ( ½ × 196 ) + ( ¾ × 22/7 × 196 )
= 98 + ( ¾ × 616 )
= 98 + 462 = 560 cm²

luas bangun = luas 3/4 lingkaran + luas segitiga siku-siku

luas 3/4 lingkaran = 3/4 x π x r x r
                             = 3/4 x 22/7 x 14 x 14
                             = 66/28 x 14 x 14
                             = 33  x 14 = 462 cm²

luas segitiga siku-siku = 1/2 x a x t
                                    = 1/2 x 14 x 14
                                    = 7 x 14 = 98 cm²

luas bangun datar = luas 3/4 lingkaran + luas segitiga siku-siku
                              = 462 + 98 = 560 cm²
