Question

find the perimeter. simplify your answer. 1 b - 4 b - 4 1

Explanation:

Step1: Recall perimeter formula

For a rectangle, the perimeter formula is $P = 2(l + w)$, where $l$ is the length and $w$ is the width. Here, $l=b - 4$ and $w = 1$.

Step2: Substitute values into formula

$P=2((b - 4)+1)$.

Step3: Simplify the expression inside parentheses

$(b - 4)+1=b-4 + 1=b - 3$. So, $P = 2(b - 3)$.

Step4: Distribute the 2

Using the distributive property $a(b - c)=ab-ac$, we have $P=2b-6$.

Answer:

$2b - 6$
