This is a great question!
If x were the length of this rectangle, then we could conclude the following,
2( 38 ) + 2( x ) > 692,
As you can see there is a greater than sign present, as the perimeter is at least 692 centimeters. In this case the perimeter is given to be at least 692 centimeters, but can also be calculated through double the width and double the length together. And of course we are given the width to be 38 cm -
2( 38 ) + 2x > 692,
76 + 2x > 692,
2x > 616,
x > 308
<u><em>Solution = Length should be at least 308 cm</em></u>

Answer:
0.4
Step-by-step explanation:
to convert from a fraction to a decimal, we first have to make the denominator 100
we know that 5 goes into 100 20 times ;
100 ÷ 5 = 20 ;
then we have to multiply the numerator by 20 as well because we have multiplied the bottom by 20 ;
2 x 20 = 40 ;
=
then to convert this into a decimal, divide the numerator by the denominator
40 ÷ 100 = 0.4
