Question

find the perimeter. simplify your answer.
the figure is a rectangle with length y - 7 and width y - 8 (the sides are labeled: top and bottom are y - 7, left and right are y - 8).

Explanation:

Step1: Identify rectangle sides

Length = $y-7$, Width = $y-8$

Step2: Use perimeter formula

Perimeter = $2×(length + width)$

Step3: Substitute values

$2×[(y-7)+(y-8)] = 2×(2y - 15)$

Step4: Simplify expression

$4y - 30$

Answer:

$4y - 30$
