hitunglah luasnya #tolongyhkk #terimakasih

L1 = p×l
= 40 × 20
= 800

L2 = p×l
= 25 × 20
= 500

L3 = p×l
= 20 × 18
= 360

Luas Seluruh = 800 + 500 + 360 = 1660 cm²

Semoga Membantu :) Maaf kalo slh
Di Koreksi lagi yaa

L1 ; p×L=40×20= 600
L2:p×L=20×25=500
L3;p×L=20×18=360
jadi seluruh nya=600+500+360=1.460
