Question

value: 2
find the perimeter of the quadrilateral.
o a. 24
o b. 6
o c. 10
o d. 20

Explanation:

Step1: Count side - lengths

Count the number of grid - units for each side. The horizontal side lengths are 6 units each and the vertical side lengths are 4 units each.

Step2: Use perimeter formula

The perimeter $P$ of a quadrilateral (rectangle in this case) is $P = 2l+2w$, where $l$ is the length and $w$ is the width. Here, $l = 6$ and $w = 4$. So $P=2\times6 + 2\times4$.
$P=12 + 8$.
$P = 20$.

Answer:

d. 20
