Answer
Area of the Triangle = $A$ = 52 yd$^{2}$
Perimeter of the Triangle = $P$ = 34 yd
Work Step by Step
Area of a Triangle: $A$ = $\frac{1}{2}$$b$$h$
Therefore:
$A$ =$\frac{1}{2}$(13 yd)(8 yd)
$A$ = 52 yd$^{2}$
Perimeter of a Triangle: $P$ = $a$ + $b$ + $c$
Therefore:
$P$ = 9 yd + 12 yd + 13 yd
$P$ = 34 yd
