Answer 2

Answer:

961 cm²

Step-by-step explanation:

$\text{Let the side of the square be a. Then, perimeter = 4a}\\\\\text{But given perimeter = 124 cm}\\\\\therefore \: 124 = 4a\\\\\implies a = 124 \div 4 = \boxed{31 \: cm}\\\\\text{Therefore, area = a ^2 = (31) ^2 = } \boxed{\boxed{\bold{961 \: cm^2}}}$
