tolong jawab pake cara ya

tinggi trapesium (alas)
= akar 5² - 4² = 3cm

luas permukaan prisma
= 2 * (6+14)* 3/2 + (5+5+14+6)15
= 60 + 450
= 510cm²

Lp prisma= 2 x La + Ka x t
                = 2 x (1/2 (a + b) x t + Ka x t
                = 2 x (1/2 (14 + 6) x 3 + (5 + 5 + 14 + 6)
                =60 + 450
                = d. 510 cm²
