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,
$\frac{10 \times 12}{2} \\ = 60 {m}^{2}$

Answer:

0.65 square inch

Step-by-step explanation:

Each triangle has an area given by ...

A = 1/2bh = 1/2·(0.5 in)(0.4 in) = 0.10 in²

The square base has an area given by ...

A = s² = (0.5 in)² = 0.25 in²

The total area is that of the square base and 4 triangles:

S = 0.25 in² + 4×0.10 in² = 0.65 in²
