Question

The ares of a rectangle is 46 square inches, if the length is 4 times the width , the find the dimensions of the rectangle.

Answer 1

Answer:

$\sqrt{11.5} =w$ (Width)

$4\sqrt{11.5}= Length$

Step-by-step explanation:

Area of a rectangle: 46 = w(L)

L = 4w

Substitute

46 = 4$w^{2}$

Divide both by 4

$11.5=w^{2}$

$\sqrt{11.5} =w$ (Width)

$4\sqrt{11.5}= Length$
