Determine the area of squre ABCD with AB=3cm

The area of the square is 2.25cm

Step-by-step explanation:

Here's what we know:

-Each letter represent a side

-A square is made up of 4 congruent sides

-To find the area of a square you need 2 sides

-We have 2 sides (A and B)

Now we can solve:

If 3cm is the length of A and B together, then we can determine that separately The sides are 1.5cm. We can then multiply 1.5 by itself to get 2.25cm.
