11. luas persegi = s x s
= 3 x 3
= 9 cm
luas persegi panjang = p x l
= 10 x 4
= 40 cm
=> luas persegi + luas persegi panjang
= 9 + 40
= 49 cm
keliling persegi = 4 x s
= 4 x 3
= 12 cm
keliling persegi panjang = 2x (p+l)
= 2x (10+4)
= 2x40
= 80 cm
=> keliling persegi + keliling persegipanjang
= 12 + 80
= 92 cm
