Answer:
4096 cm²
Explanation:
Perimeter of a square is given by the formula :
P = 4a
Now we substitute P To solve for a :
256 = 4a
a = 256÷4
a = 64
Area of a square is given by the formula :
A = a²
Now we substitute the value of a worked out from perimeter to work out the area :
A = 64²
A = 64×64
A = 4096
Units will be cm² as it is area
Hope this helped and have a good day
