A square has a perimeter of 12 cm. What is its area?

a. 9 cm 2
b. 18 cm 2
c. 36 cm 2
d. 144 cm 2

Answer 1

hello : answer : a) 9 cm 2

Explanation:

A square has a perimeter of 12 : p = 4×c.....c is the length

12 = 4c

c = 12/4

c = 3

the area A= c²

A= 3² = 9 cm 2

Answer 2

a. 9 cm 2 because each side would be 3 and length x width would be 3 x 3 = 9
