The length of a rectangle is three times of its width. If the length of the diagonal is 8sqrt(10)m , then the perimeter of the rectangle is: (a) 15sqrt(10) m (b) 16sqrt(10) m (c) 24sqrt(10) m (d) 64 m

A triangle and a parallelogram are constructed on the same base such that their areas are equal.If the altitude of the parallelogram is 100m, then the altitude of the triangle is 10sqrt(2)m(b)100m(c)100sqrt(2)m(d)200m

If the diagonal of a square is sqrt(8) metre,then its area is: 8m^(2)( b) 4m^(2)( c) 16m^(2)( d) 6m^(2)

The area of a square is twice that of a rectangle. The perimeter of the rectangle is 10 cm. If its length and breadth each is increased by 1 cm, the area of the rectangle becomes equal to the area of the square. The length of side of the square is 2sqrt(3)c m (b) 3sqrt(2)c m (c) 4sqrt(3)c m (d) 12 cm
