the length of the rectangle is 5 less than twice its width. the perimiter is 26 meters. find the dimensions of the rectangle

Respuesta :

Answer:

the length is 7 meters and the width is 6 meter

Step-by-step explanation:

1)Make a system of equations...

L=length W=width

2L+2W=26

2W-5=L

2) Substitute 2W-5 for L in the first equation...

2(2W-5)+2W=26

3)Simplify...

6W-10=26

4)Solve for W...

6W=36

W=6 meters

5)Plug 6 back into the first equation to get L...

2L+2(6)=26

2L+12=26

2L=14

L=7 meters
