Question

The perimeter of a rectangle equals one and a half times its area. Express the length of the rectangle in terms of the width (use the variable ???? for the width).

Answer 1

Answer:

Step-by-step explanation:

let x and y be length and width of rectangle.

Perimeter=2(x+y)

area=xy

2(x+y)=1/2 xy

4(x+y)=xy

4x+4y=xy

x y-4y=4 x

y(x-4)=4 x

$y=\frac{4x}{x-4}$
