Verified answer

K trapesium = 18+36+15+15
                    = 84 cm


K lingkaran = 3,14×2×100
                   = 6,28×100
                   = 628 cm


L segitiga = (24×18)÷2
                 = 432÷2
                 = 216 cm²


L jajrgenjang = a×t
                      = 15×8
                      = 120 cm²
L persegi = s²
                = 10²
                = 100 cm²
L gabungan = 120+100
                    = 220 cm²
