Question

1. find the perimeter of the triangle. 7cm, 8cm, 16cm (triangle diagram omitted)

Explanation:

Step1: Recall perimeter formula

The perimeter \( P \) of a triangle is the sum of its three side lengths. So \( P = a + b + c \), where \( a \), \( b \), and \( c \) are the lengths of the sides.

Step2: Identify side lengths

The side lengths are \( 7\,\text{cm} \), \( 8\,\text{cm} \), and \( 16\,\text{cm} \).

Step3: Calculate the perimeter

Substitute the values into the formula: \( P = 7 + 8 + 16 \). First, \( 7 + 8 = 15 \), then \( 15 + 16 = 31 \).

Answer:

The perimeter of the triangle is \( 31\,\text{cm} \).
