Use dimensional analysis to convert the quantity to the indicated units 27in to yd

There is 12 inches in 1 foot.

There is 3 feet in 1 yard.

12 inches divided by 1 foot = 27 inches divided by x feet.

12/1 = 27/x

12 = 27/x

12x = 27

x = 27/12

x = 2.25 feet

3 feet divided by 1 yard = 2.25 feet divided by x yards.

3/1 = 2.25/x

3 = 2.25/x

3x = 2.25

x = 2.25/3

x = 0.75

The answer is already rounded to the nearest hundredth so the answer is:

0.75 yd

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
