The length of a rectangle is 1 foot more than twice the width the perimeter is 44 feet find the dimensions of the rectangle

Annette [7]

The length of rectangle is 15 feet and width is 7 feet.

Step-by-step explanation:

Given,

Width of rectangle = w

Length of rectangle = 2w+1

Perimeter = 44 feet

Perimeter = 2(Length+Width)

$Perimeter=2(2w+1+w)\\44=2(3w+1)\\44=6w+2\\44-2=6w\\42=6w\\6w=42$

Dividing both sides by 6

$\frac{6w}{6}=\frac{42}{6}\\w=7$

The width of rectangle is 7 feet.

Length of rectangle = 2(7)+1 = 14+1 = 15 feet

The length of rectangle is 15 feet and width is 7 feet.
