Step-by-step explanation:

Given :-

  • Let width be x and length be 5x - 10 according to the question

To find:-

  • Measurement of length and width

Solution :-

Formula for perimeter of rectangular swamp = 2(L+W)

  • Putting the known values ,

124 ft. = 2( 5x -10 + x )

124 ft. = 2(6x - 10)

124 ft. = 12x - 20

124+20 = 12x

144/12 = x

12 = x

putting the values of x

Length = 5x-10

  • 5×12 - 10 = 50 feet

width = X

  • 12 feet

perimeter =2L+2W or 2(L+W)

124= 2(5W-10+W)

perimeter =2( 6W-10)

124 = 12W-20

124+20=(12W+20-20

144=12W

144÷12=12W÷12

12=W
