Question

Anyone know the area?

Answer 1

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

                                         or, write as:  " 8$\frac{1}{2}$ cm² " .

Explanation:
_________________________________________________________
The formula {"equation"} for the area of a triangle is:

A = ($\frac{1}{2}$) * 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$\frac{1}{2}$ cm² " .
