A square park has an area equal to the area of a rectangle whose length exceeds its breadth by 9 m and the breadth is half the side of the square. Find the side of the square.

The sides of a triangle are in the ratio of 1/9:1/11:1/13 and its perimeter is 718 cm . Find the length of its longest side in metre.

The ratio of the length of each equal side and the third side of an isosceles triangle is 5:6. If the area of the triangle is √11664 sq.cm., then the length of the third side (in cm ) is:
