1 ) L = 1/2 x a x t 300 = 1/2 x a x 400 300 = 200a 200a = 300 a = 1,5cm Jadi alasnya 1,5cm 3 ) L = d1 x d2 2 = 15 x 18 2 = 135cm² 4) L.= 1/2 x t ( a + b ) = 1/2 x 7 ( 17 + 10 ) = 1/2 x 7 x 27 = 1/2 x 189 = 94,5cm
300 = 1/2 x a x 400
300 = 200a
200a = 300
a = 1,5cm
Jadi alasnya 1,5cm
3 ) L = d1 x d2
2
= 15 x 18
2
= 135cm²
4) L.= 1/2 x t ( a + b )
= 1/2 x 7 ( 17 + 10 )
= 1/2 x 7 x 27
= 1/2 x 189
= 94,5cm
