Tolong bantuannya ya

OD² = 10²-6²
OD² = 100-36
OD = √64 = 8

OB = OD = 8

OE² = 17²-8²
OE² = 289-64
OE = √225 = 15

Ljajargenjang = a×t
= AB×OE
= 20×15
= 300 cm²

Llayanglayang = d1×d2×½
= (OC+OE)×(OB+OD)×½
= (6+15)×(8+8)×½
= 21×16×½
= 168 cm²

Ltotal = 300+168
= 468 cm²

Hasil penjualan = 468×425000
= 198.900.000
