The length of a rectangle is 6 inches less than twice its width, and the perimeter is 72. What are the dimensions of the rectangle?

Length=22 inches and width=14 inches

Step-by-step explanation:

According to the 1st condition

Perimeter=72

or, 2(l+b)=72

or, l+b=36equation(i)

According to second condition

l=2b-6equation(ii)

Substituting the value of l form equation (i) to equation(ii)

2b-6+b=36

b=14

l=2*14-6

=22

down below!

Step-by-step explanation:

if the:                          if the :

length:14                    length:15

width:20                    width:21

                                      perimeter: 15+15+21+21=        72cm  

                                             please mark me as brainliest!!<3

perimeter:14+14+20+20=

68cm

do i do it on a graph?
