Question

Perimeter of a square is 256cm. what is its area​

Answer 1

Answer:

4096 cm²

Step-by-step 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

Answer 2

Answer:

4,096cm

Step-by-step explanation:

/ means divide

* means multiply

formula for finding area: length * width

Divide by 4 since a square has 4 sides: 256 / 4 = 64

length times width: 64 * 64 = 4,096
