If the two parallel sides of the square is increased by 5 cm, then the area of the rectangle will be 750 Sq. cm. Find the area of the square.
Answer: B . 625 Sq. cmTweet
Area of the Rectangle = L * B = (B + 5) * B = 750
=> B^2 + 5B - 750 = 0
=> (B + 30) * (B - 25) = 0
=> B = 25
Now the area of the Square = B * B = 25 * 25 = 625 Sq. cm.
