Answer:
225cm²
Step-by-step explanation:
A square is a type of quadrilateral( polygon with 4 sides) that has all his sides equal.
Area of a square = length x breadth
But since all sides are equal
Therefore breadth = length
This means that area of square = length x length or area = square of the length
Given that length= 15cm
Therefore area of the square = 15cm x 15cm
Area = 225cm²
Area of a square with length 15cm is 225cm²
