Question

what is the perimeter of the rectangle shown on the grid? units

Explanation:

Step1: Determine length and width

The length of the rectangle is from $y = - 1$ to $y = 5$, so the length $l=5 - (-1)=6$ units. The width of the rectangle is from $x=-2$ to $x = 2$, so the width $w = 2-(-2)=4$ units.

Step2: Use perimeter formula

The perimeter formula of a rectangle is $P = 2(l + w)$. Substitute $l = 6$ and $w = 4$ into the formula: $P=2(6 + 4)$.

Step3: Calculate perimeter

$P=2\times10 = 20$ units.

Answer:

20
