Find the area of the square, the length of whose diagonal is 25 cm.
A
312.5 sq.cm
B
317.5 sq.cm
C
318.5 sq.cm
D
319.5 sq.cm
Solution:
Concept- We are aware that if a square's side length is equal to x, then the square's area is equal to . Now that we have the idea, we can calculate the required square's area. It is evident from the diagram that the square's diagonal measures 25 cm in length. Area of square = Hence, the correct answer is option 1.
