Suppose you are an elementary school teacher. you want to order a rectangular bulletin board to mount on a classroom wall that has an area of 250 square feet. suppose fire code requirements allow for no more than 30% of a classroom wall to be covered by a bulletin board. if the length of the board is three times as long as the width, what are the dimensions of the largest bulletin board that meets fire code?

astronomers is your final answer! : )

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 .
