The room above is shaped like a rectangle and has a perimeter of 34 feet. if the room is 11 feet long, how wide is it?

6 feet

Step-by-step explanation:

The perimeter of a rectangle = 2l + 2w

where l is the length and w the width

here perimeter = 34 and length = 11, hence

2 × 11 + 2w = 34

22 + 2w = 34 ( subtract 22 from both sides )

2w = 12 ( divide both sides by 2 )

w = 6

That is the width of the room is 6 feet

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
