Diketahui :Lp = 3.620 cm²p = 40 cmt = 15 cmDitanya : lebar = ?Penyelesaian : → 2(pl + lt + tp) = Lp→ 2(40l + 15l + 40 × 15) = 3.620 cm²→ 2(55l + 600) = 3.620 cm²→ 110l + 1.200 = 3.620 cm²→ 110l = 3.620 - 1.200 cm²→ 110l = 2.420 cm²→ l = 22 cm[tex]\purple{\boxed{\blue{\boxed{\green{\star{\orange{\ \: \: \mathcal{JK} \: \: \: {\green{\star}}}}}}}}} [/tex]
