Natoshia's den is 4 feet longer than it is wide. If the den's area is 320 square feet, what are the dimensions of the room?

julsineya [31]

Dimensions : 16 x 20

Let the width be x

then the length: x + 4

<h3> area of rectangle = Length * Width</h3>

solving steps:

(x+4)(x) = 320

x² + 4x = 320

x² + 4x - 320 = 0

x² +20x -16x -320 = 0

x(x + 20) -16(x+20) = 0

(x-16)(x+20) = 0

x = 16, -20

x = 16 [ As length or width can never be negative ]

<u>So we found Width = 16 feet</u>

Length:

16 + 4

20 feet
