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 17 cm, 10 cm, and 21 cm.
$P = 17 + 10 + 21$
$P = 48$ cm

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 21 cm and the height is 8 cm.
$A = \frac{1}{2} \times 21 \times 8$
$A = 84$ $cm^2$

Answer:

Perimeter $P = 48$ cm
Area $A = 84$ $cm^2$
