Question

what is the perimeter of the rectangle? 19 cm 17 cm a 36 cm b 72 cm c 62 cm d 323 cm

Explanation:

Step1: Recall perimeter formula for rectangle

The formula for the perimeter \( P \) of a rectangle is \( P = 2\times (length + width) \). Here, length \( l = 19\space cm \) and width \( w = 17\space cm \).

Step2: Substitute values into formula

Substitute \( l = 19 \) and \( w = 17 \) into the formula: \( P = 2\times(19 + 17) \). First, calculate the sum inside the parentheses: \( 19 + 17 = 36 \). Then multiply by 2: \( 2\times36 = 72 \).

Answer:

B. 72 cm
