Question

what is the perimeter of the rectangle? 14 cm 9 cm a 126 cm b 136 cm c 23 cm d 46 cm

Explanation:

Step1: Recall the perimeter formula

The perimeter formula of a rectangle is \(P = 2\times(l + w)\), where \(l\) is the length and \(w\) is the width.

Step2: Substitute the values

Here, \(l = 14\) cm and \(w=9\) cm. So \(P = 2\times(14 + 9)\).
First calculate the sum inside the parentheses: \(14+9 = 23\).
Then multiply by 2: \(2\times23=46\).

Answer:

D. \(46\) cm
