Answer 1

Answer:

Area of the triangle = 26 cm²

Step-by-step explanation:

The given triangle has the measure of height h = 4 cm

and base of the triangle = 13 cm

We know the formula of the area of a triangle = $\frac{1}{2}(Base)(height)$

By putting the values in the formula

Area of the triangle = $\frac{1}{2}(4)(13)$

                                = 2×13

                                = 26 cm²

Therefore, area of the given triangle is 26 cm².

Answer 2

As you can see there are two triangles but it can be done calculating just for one. First we must understand how formula for area of triangle works.

$A=\frac{1}{2}bh$

Where $b$ represents base (hypotenuse) and $h$ as height of the triangle.

We know that:

$b=13cm \\h=4cm$

Using this data we fill the formula.

$A=\frac{1}{2}\cdot13\cdot4=\frac{13\cdot4}{2}=13\cdot2=\boxed{26cm^2}$

Hope this helps.
