Answer: The area of the triangle is: " 8.5 cm² " ;

or, write as: " 8
(1)/(2) cm²
" .
_______________________________________________________
Step-by-step explanation:
_________________________________________________________
The formula {"equation"} for the area of a triangle is:

A = (
(1)/(2)) * b * h ;

in which: A = area;
b = base;
h = [perpendicular] height;
___________________________________
{also, can be written as: " A = (b * h) / 2 " .}.
______________________________________
Solve for the area, "A" ; by plugging in the known values shown in the figure (image attached):
______________________________________
base, "b" = 13 cm ;
[perpendicular] height, "h" = 5 cm ;
______________________________________
A = (b * h) / 2 ;

= (13 cm * 5 cm) / 2 ;

= [ (13 * 5) cm²] / 2 ;

= 65 cm² / 2 ;

A = " 8.5 cm² " ; or, write as: " 8
(1)/(2) cm²
" .
