Q.13)First,we need to factor out 900 which will be 2×2×3×3×5×5 now we can observe that 2×3×5 = 30 is required to be multiplied by 900 to get a perfect cube.So x = 30
Q.14)We first take the LCM which in this case is 720.Now we factorize it = 2×2×2×2×3×3×5,we can observe that 5 is required to multiplied by 720 to get a perfect square,the answer is 720 × 5 = 3600
Q.15)Let the side be s,then s×s = 605.16
=>s^2 = 605.16 =>s = √605.16 = 24.6
So Side = 24.6,then the Perimeter = 4 × 24.6 = 98.4 metres.
