Answer:
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.
Hope this helps :)
