Answer:
$77\ \text{sq. units}$

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.
$(1)/(2)\pi r^2$

Put the value

$\Rightarrow (1)/(2)*\pi * 7^2=76.97\\\Rightarrow \approx 77\ \text{sq. units}$

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