a. L = s x s = 14 x 14 = 196 cm persegi
b. L = 22 x 22 = 484 cm persegi
c. L = 8,4 x 8,4 = 70,56 cm persegi
d. L = 7,5 x 7,5 = 56,25 cm persegi

a)
L = s × s
L = 14 × 14
L = 196 cm^2

b)
L = s × s
L = 22 × 22
L = 484 cm^2

c)
L = s × s
L = 8,4 × 8,4
L = 70,56 cm^2

d)
L = s × s
L = 7,5 × 7,5
L = 56,25 cm^2
