Question

a parallelogram has sides of length 12 inches and 19 inches. what is the perimeter? inches submit

Explanation:

Step1: Recall perimeter formula for parallelogram

A parallelogram has opposite sides equal. So perimeter \( P = 2(a + b) \), where \( a \) and \( b \) are side lengths.

Step2: Substitute values into formula

Here, \( a = 12 \) inches, \( b = 19 \) inches. So \( P = 2(12 + 19) \).

Step3: Calculate the sum inside the parentheses

\( 12 + 19 = 31 \).

Step4: Multiply by 2

\( 2 \times 31 = 62 \).

Answer:

62
