Question 188044: An envelope is 5cm longer tha it is wide. The area of the entire envelope is 66cm. What are the measures of the length and width? Answer by feliz1965(151) (Show Source):
You can put this solution on YOUR website! This envelope is a rectangle because the words width and length are used in the word problem.
The area of a rectangle is found using A = LW.
width = x
length = x + 5
I will set it up and you can finish.
66 = (x + 5)(x)
Can you finish now?
