Ada lgi nih tolong Yaa??

L.alas = ½ x a x t
48 = ½ x a x 8
48 = 4a
a = 48/4
a = 12 cm
a = BC = 12cm

AB² = AD² + BD²
AB² = 8² + 6²
AB² = 64 + 36
AB² = 100
AB = ®100
AB = 10cm

® = root = akar

Lp= (2 x luas alas) + ( t x BC) + ( 2 x AB x t)

= (2 x 48) + (25 x 12) + (2 x 25 x 10)
=96 + 300 + 500
= 896cm²
