Question 1006815: A rectangle is 6 metres longer than its breadth. The perimeter of this rectangle is 72 metres. What is the length of the rectangle? Answer by Cromlix(4381) (Show Source):
You can put this solution on YOUR website! Hi there,
Make the breadth = 'x'
Length = 6 + x
Perimeter = 2(breadth) + 2(Length)
72 = 2(x) + 2(6 + x)
72 = 2x + 12 + 2x
Collect like terms:
2x + 2x = 72 - 12
4x = 60
x = 15
Breadth = 15m
Length = 21m
Hope this helps :-)
