The length of a rectangle is 3 more inches than the width. find the length and width of the rectangle is the perimeter of the rectangle is 54 inches. #7 write an equation that represents the situation. explain any variable used. #8 solve the equation. show your work. state your solution as a complete sentence

Part A:

Let the width of the rectangle be = x inches

As given, the length of a rectangle is 3 more inches than the width so let the length of the rectangle be = x+3 inches

Perimeter is given as = 54 inches

Perimeter =

Equation becomes:

=54

Part B:

Solving the equation we get

Hence, the width of the rectangle is 12 inches

Length = x+3 = 12+3 = 15 inches

Hence, length of the rectangle is 15 inches.
