Let’s break it down! First, let’s define the variables: let the width be \( w \) inches. According to the problem, the length can be expressed as \( 2w - 6.75 \) inches. The formula for the perimeter of a rectangle is \( P = 2 \times (length + width) \). Setting it equal to 118.5 inches gives us: \[ 2(2w - 6.75 + w) = 118.5 \] Simplifying that: \[ 2(3w - 6.75) = 118.5 \] \[ 6w - 13.5 = 118.5 \] \[ 6w = 132 \] \[ w = 22 \] inches (width) Now plug that back into the length formula: \[ length = 2(22) - 6.75 = 44 - 6.75 = 37.25 \] inches. So, the width is 22 inches and the length is 37.25 inches! Great job working through that; keep practicing and those algebraic skills will be sharper than ever!
