Question

Bantuin jawaban no 4 dong sama penyelesaiannya yaa

Answer 1

GK/AH = EG/EH
GK/9 = 18/27
GK = 18. 9 /27
GK = 6

FL/ AH = EF/EH
FL/9 = 9/27
FL = 9 . 9/27
FL = 3

Luas Trapesium KLFG
= (GK + FL) GF/2
= (3 + 6) 9/2
= 81/2
= 40,5

Luas segitiga BCM
= MC . BC/2
= 4,5 . 9/2
= 20, 25

Luas persegi BCFG
= 9 x 9 = 81

KBML = BCFG - BCM - KLFG
            = 81 - 20,25 - 40,5
            = 20,25 cm²
