5 times of the perimeter of a square is 600 cm. What will be the area of this square?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 900 cm2.
Perimeter of square = 4a
Area of square = a2
Where a = side
According to the question;
⇒ 5 × perimeter of square = 600
⇒ 5 × 4 × a = 600
⇒ a = 30
Area of square = 30 × 30 = 900 cm2
