What are the dimensions of the garden?

Question

A rectangular garden has a length that is 5 less than twice the width, the garden perimeter is 50 meters.

Answer 1

P = 2L + 2W

 

 

50 = 2(2w-5) + 2w <---- Periemter is 50; Length is 5 less than twice the width, so L = 2w-5

 

50 = 4w - 10 + 2w

 

50 = 6w - 10

 

60 = 6w

 

w = 10

 

width is 10, length is 2(10)-5 = 20 -5 = 15
