Question

1. a rectangle is 15 feet wide and 18 feet long. find the perimeter of the rectangle.

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 $l = 18$ feet and $w = 15$ feet, we substitute into the formula: $P=2(18 + 15)$.

Step3: Calculate sum inside parentheses

First, calculate $18+15 = 33$. So $P = 2\times33$.

Step4: Multiply

$2\times33=66$.

Answer:

66 feet
