Question

What is the area of a triangle with a height of 13 cm and a base of a 10 cm?

Answer 1

Area of a triangle is equal to 1/2 b(h) so since you already have the height and base, all you need to do is input it back into the equation:

$\frac{1}{2}$ (10)(13)


Multiply 10 & 13 to equal 

$\frac{1}{2}$ (130)

Then take half of 130 to get

A = 65 $cm^{2}$

Answer 2

Greetings!

The Formula for the Area of a Triangle is: $A= \frac{bh}{2}$

Input the values we already know:
$A= \frac{10*13}{2}$

Solve for A.
$A= \frac{130}{2}$

$A= \frac{130}{2}$

$A=65$

The Answer Is:
$\left[\begin{array}{ccc}A=65\end{array}\right]$

The Area of the Triangle is 65 cm²

Hope this helps.
