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.

Keywords: rectangle, perimeter

Answer answer please please
tamaranim1 [39]

Answer:

B. <

Step-by-step explanation:

2.7 * 10^3 is < 27 * 10^3

since

27 * 10^3 = 27000

2.7 * 10^3 = 2700

2700 < 27000

now since multiplying by 10 moves the decimal to the right, just looking and mentally comparing them. since they are both multiplied by 10^3 you're left with 2.7 and 27

27 is greater than 2.7

so

your answer is B or <

hope this helps :)
