Question 37072: A rectangle is 7 times as long as it is wide. Its area is 1400cm squared. Find the dimensions of the rectangle in simplest form. Answer by Paul(988) (Show Source):
You can put this solution on YOUR website! Length is 7x and the width is x
Equation:
(7x)(x)=1400
7x^2=1400
x^2=200
x=14
7(14)=98
Hence, its length is 98 and its width is 14 (rounded).
Paul.
