Answer:

width = w

length= 3w+1

perimeter= 5(3w+1) -45

perimeter     =   2(l+b)

5(3w+1) -45 = 2{(3w+1)+w}

  15w  - 40   =  8w+2

             6w  = 42

               w  =7

therefore width = <u>7</u>

 length= 3w+1  =  <u>22</u>

perimeter=  <u>65</u>

100 POINTS!!! Which statement about rational numbers is correct?
Natasha_Volkova [10]

Answer: Rational numbers have decimal expansions that repeat or terminate.

Step-by-step explanation:

The explanation of this is the non-terminating but repeating decimal expansion means that although the decimal representation has an infinite number of digits, there is a repetitive pattern to it. The rational number whose denominator is having a factor other than 2 or 5, will not have a terminating decimal number as the result.
