Question 953834: The length of a rectangle is three times longer than its width if the area of the rectangle is 24 in.² then what is the perimeter of the rectangle? Answer by bijaysumi(6) (Show Source):
You can put this solution on YOUR website! Let the width is x
Length=3x
Area=x*3x=3x^2=24 sq in
X^2=24÷3=8
X=√8=2√2
and length= 6√2
Perimeter= 2(2√2+6√2)
=2√2(2+8)
2√2×10
=20√2 inch
