The perimeter of a rectangle is 34 units. Its width is 6.5 units

Question

Write an equation to determine the length (L) of the rectangle. Then find the length of the rectangle  

Answer 1

The perimeter includes 2w, and w=6.5 so the perimeter can be reduced by 2w=13, giving 2L.

 

You should be able to determine L.

 

P = 2w + 2L; substitute for P and w, and solve for L.
