Question

compute the perimeter and area of the triangle shown. include units in your computations and answer. how to enter an answer with units

Explanation:

Step1: Calculate the perimeter

The perimeter of a triangle is the sum of its three sides. The sides are 42 mi, 39 mi, and 50 mi.
$P = 42 + 39 + 50$
$P = 131$ miles

Step2: Calculate the area

The area of a triangle is given by the formula $A = \frac{1}{2} \times base \times height$. Here, the base is 39 mi and the height is 40 mi.
$A = \frac{1}{2} \times 39 \times 40$
$A = 39 \times 20$
$A = 780$ square miles

Answer:

Perimeter $P = 131$ miles, Area $A = 780$ square miles
