Step-by-step solution

3 steps

  1. Calculate the first expression

    Substitute a=4a=4 into (2a+1)(2a+1)

    2a+1=2(4)+1=8+1=92a+1 = 2(4)+1 = 8+1 = 9

    The first length is 9 सेंटीमीटर\boxed{9\ \text{सेंटीमीटर}}

  2. Calculate the second expression

    Substitute a=4a=4 into (3a−1)(3a-1)

    3a−1=3(4)−1=12−1=113a-1 = 3(4)-1 = 12-1 = 11

    The second length is 11 सेंटीमीटर\boxed{11\ \text{सेंटीमीटर}}

  3. Calculate the third expression

    Substitute a=4a=4 into (3a+1)(3a+1)

    3a+1=3(4)+1=12+1=133a+1 = 3(4)+1 = 12+1 = 13

    The third length is 13 सेंटीमीटर\boxed{13\ \text{सेंटीमीटर}}
