Question

A rectangular soccer field is twice as long as it is wide. If the perimeter of of the soccer field is 300 yards, what are its dimensions?

Answer 1

A) L = 2WB) 2L + 2W = 300
Multiplying A) by -2A) -2L = -4WThen adding it to B)B) 2L + 2W = 3002W = 300 -4W
6W = 300Width = 50Looking at equation A) we calculate
Length = 100
