Question

The perimeter of a rectangle equals the sum of the lengths of its four sides. If the width of a rectangle is 8 inches and its perimeter is 46 inches, find the length of the rectangle in inches

Answer 1

subtract 16 from 46 then divide by two

Answer 2

\[length + length + width + width = perimeter\]
\[l + l + 8 + 8 = 46\]
\[2l + 16 = 46\]
\[2l = 46 - 16\]
\[2l = 30\]
\[l = ?\]
