Question

find the perimeter of the rectangle. include the unit. 12 cm 19 cm

Explanation:

Step1: Recall perimeter formula

The formula for the perimeter \(P\) of a rectangle is \(P = 2(l + w)\), where \(l\) is the length and \(w\) is the width. Here \(l=19\) cm and \(w = 12\) cm.

Step2: Substitute values

Substitute \(l = 19\) and \(w=12\) into the formula: \(P=2(19 + 12)\).
First, calculate the sum inside the parentheses: \(19+12=31\). Then, multiply by 2: \(P = 2\times31=62\).

Answer:

62 cm
