Answer
$A=274.1m^{2}\approx274m^{2}$
$P=82.3m$
Work Step by Step
To find the area of the triangle, we use the formula:
$A=\frac{bh}{2}$
So,
$A=\frac{bh}{2}=\frac{(19.1m)(28.7m)}{2}=274.1m^{2}\approx274m^{2}$
To find the perimeter, we add the lengths of all the sides.
However, we are missing the hypotenuse of the triangle, so we use the Pythagorean Theorem to find it.
$c^{2}=a^{2}+b^{2}$
$c=\sqrt {a^{2}+b^{2}}=\sqrt {(19.1m)^{2}+(28.7m)^{2}}=34.47m\approx34.5m$
$P=19.1m+28.7m+34.5m=82.3m$
