Question 941555: The width of a rectangular lawn is 15 meters less than the length. Find the dimensions of the lawn if the perimeter is 86 meters. Answer by srinivas.g(540) (Show Source):
You can put this solution on YOUR website! let x be the length of rectangular
width =x-15
perimeter = 86 meters
formula : perimeter = 2( length+width)
86 = 2(x+(x-15))
86 =2(2x-15)
86 =4x-30
86+30 = 4x
116 = 4x
divide with 4 on both sides
length (x) =29 m
width (x-15) = 29-15
= 14 m
Result : length =29 m , width = 14 m
