Answer 1

22 cm x 22 cm - ( {34 cm x 12cm/2} + {22cm x 10cm/2 } )
= 484 cm^2 - (204 cm^2 + 110 cm^2)
= 484 cm^2 - 314 cm^2
= 170cm^2

Answer 2

Luas persegi=s²=22²=484 cm²
LΔ=1/2 a x t
    =1/2 22 x 10
    =1/2 x 220
    =110 cm²
Ltrap=1/2 (a+b) x t
    =1/2 (22+12) x 12
    =1/2 x 34 x 12
    =1/2 x 408
    =204 cm²
Larsir=484-(110+204)
        =484-314
        =170 cm²
