tolong bantuin yaaaaaa

L1= persegi panjang
  = P·l
  =30·25
  =750
L2= 1/2 πr²
    =1/2 ·3,14·15²
    =1/2·3,14·225
    =353,15
luas gabungan= L1+L2
                        =750+353,25
                        =1.103,25

L1 = Persegi panjang
= P x l
= 30 x 25 = 750 cm

L2 = Setengah lingkaran
= π x r²
= 22 per 7 x 21 x 21

= 2.826 cm²
