the perimeter of a rectangle is 46. the length is one less twice the width. what are the demensions?

Question

i need help with some mathematical questions please

Answer 1

Let the width be x

 

then the length ='2x-1

 

2(2x-1)+2x=46

 

4x-2+2x=46

 

6x=48

 

x=8

 

width=8

 

length 2(8)-1

 

= 15
