Question

find the perimeter of the quadrilateral. simplify your answer. 4c + 9 7c - 5 5c + 2 5c - 3

Explanation:

Step1: Recall perimeter formula

The perimeter $P$ of a quadrilateral is the sum of the lengths of its four - sides. So $P=(4c + 9)+(7c-5)+(5c + 2)+(5c-3)$.

Step2: Combine like - terms

First, combine the $c$ terms: $4c+7c + 5c+5c=(4 + 7+5 + 5)c=21c$. Then, combine the constant terms: $9-5 + 2-3=(9 + 2)-(5 + 3)=11 - 8 = 3$.

Answer:

$21c+3$
