    Answer: 77\ \text{sq. units}

    Step-by-step explanation:

    Given

    The radius of the semi-circle is r=7

    We know, area of the circle is \pi r^2

    So, the area of the semi-circle is half of it i.e. \frac{1}{2}\pi r^2

    Put the value

    \Rightarrow \dfrac{1}{2}\times\pi \times 7^2=76.97\\\Rightarrow \approx 77\ \text{sq. units}

    The area of the semi-circle is 77\ \text{sq. units}
