The perimeter of a rectangular field is 110 feet. The length is 7 feet more than the widith. Find the dimensions. System of Equations Applications! Please help

Question

anonymous · Answer

perimeter of field = 110 ft
width = x
length = x+7
perimeter = 2x + 2(x+7) = 110
therefore when you do the above equation you come down to 4x + 14 = 110 
minus 14 from both sides you get 96
96 divided by 4 equals 24 so that's the width and add 7 to 24 and you get the length which is 31
so dimensions are 31 by 24
hope this helps! 
Cheers! ^.^
