4. Luas persegi panjang = luas persegi
L persegi panjang = 49 cm × 9 cm
= 441 cm²

L persegi = √441 cm²
sisi persegi= 21 cm

5. Nilai nining = (37-6)×2
= 31×2
=62

Nilai nunung = (40-4)×2
=36×2
=72

Nilai nanang = (38-7)×2
= 31×2
=62

nilai tertinggi= nunung 72
nilai terendah= 62

selisih = 72-62
=10
