In a scale drawing of a rectangler room the scale is 1 inch 4.5 feet find the perimeter and area of the room

Perimeter of the room = 63 ft

Area of the room = 202.5 ft²

Step-by-step explanation:

Scale of drawing = 1 in to 4.5 ft

Length of the room in the drawing = 5 in

Actual length of room = 5*4.5 = 22.5 ft

Width of the room in the drawing = 2 in

Actual length of room = 2*4.5 = 9 ft

Perimeter of the room = 2(L + W)

= 2(22.5 + 9)

= 2(31.5)

Perimeter of the room = 63 ft

Area of the room = L*W

Area = 22.5*9

Area of the room = 202.5 ft²

add an image, and i will answer

step-by-step explanation:

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
