Answer:
Area of square = 12.48 cm^2
Step-by-step explanation:
Since the square has all sides equal, and when diagonal is made, square form two right angled triangles. Using Pythagoras theorem we can find the length of side of the square.
where c = 5cm and a==b (square has all sides equal)
Putting value of b = a
So, length of side of square = 3.53
Area of square = (3.53)^2
Area of square = 12.48 cm^2.
