Question

a dance floor is in the shape of a rectangle. it is 26 meters long and 21 meters wide. what is its perimeter?

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.

Step2: Substitute values

Given $l = 26$ meters and $w = 21$ meters, we substitute into the formula: $P=2(26 + 21)$.

Step3: Calculate sum inside parentheses

First, calculate $26+21 = 47$. So, $P = 2\times47$.

Step4: Multiply

$2\times47=94$.

Answer:

94
