Does anybody know how to do question 2 please show working out

2a.
Since BC = 10m and M is the midpoint, we can find CM by : 10÷2 = 5m
So, CM = 5m

2b. Now, you have the base ( 5m) & hypotenuse (13m). Pythagoras' Theorem:

$c {}^{2} = {a}^{2} + {b}^{2}$
Where c is the hypotenuse, a & b are sides.

${13}^{2} = {5}^{2} + b {}^{2} \\ {5}^{2} + {b}^{2} = 13 {}^{2} \\ {b}^{2} = 13 {}^{2} - {5}^{2} \\ b = \sqrt{144} \\ b = 12$
b here refers to the height.

2c.
Area of a right-angled triangle =
$\frac{base \times height}{2}$
So,
$\frac{10 \times 12}{2} \\ = 60 {m}^{2}$
