On a sketch of a mural, 3 inches represents one foot in the mural. A door in the sketch is 2 inches wide by 5 inches high. What is the perimeter of the door in the mural expressed in inches?

Length of the door, l = 5 inches (in)

Width or Breadth of the door, w = 2 inches (in)

Perimeter p = 2 (l + w)

= 2 (5 + 2) inches

= 2 (5) inches + 2 (4) inches

= 10 inches + 4 inches

= 14 inches or 14 in

Step-by-step explanation:

The perimeter of a plane shape is the measurement of the length of its outside boundary, which means the distance around its edges.

The door in the sketch is the shape of a rectangle. the distance around the edge of the door is the sum of all the sides. The longer side of a rectangle is called the length and it is usually represented by letter l while the shorter side is known as width or breadth represented by letter w and b respectively. The perimeter is calculated by the formula 2 (l + w). where l means the length and w represents the width.
