Question

what is the perimeter of the triangle? 32 cm 21 cm 13 cm 11 cm 24 cm 19 cm 8 cm

Explanation:

Step1: Recall perimeter formula

The perimeter $P$ of a triangle is the sum of the lengths of its sides. Let the side - lengths be $a = 11$ cm, $b = 8$ cm, and $c = 13$ cm.

Step2: Calculate perimeter

$P=a + b + c=11+8 + 13$ cm.
$P=(11 + 8)+13=19+13 = 32$ cm.

Answer:

32 cm
