Answer
$A=48.3~cm^{2}$
$P=35.7~cm$
Work Step by Step
To find the area of a triangle, we use the formula:
$A=\frac{bh}{2}$.
Thus, we have:
$A=\frac{bh}{2}=\frac{(15.6cm)(6.19cm)}{2}=48.28~cm^{2}\approx 48.3~cm^2$
To find the perimeter, we add the lengths of all the sides:
$P=9.29cm+15.6cm+10.8cm=35.69~cm\approx 35.7~cm$
