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.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

c. side angle side. u shares the same sides
