The length of a rectangle envelope is 2 1/2 times its width. A plastic band surrounds the front and back of the envelope to secu

Andreas93 [3]

Answer:

Length of the envelope = 14

Width of the envelope = 5.6

Step-by-step explanation:

Let the width of the rectangle be x

Then the length of the rectangle will be $2\frac{1}{2} \times x$

Also the length of the plastic band to cover the front and back of the envolpe = $39\frac{3}{8}$

To cover one side th band required is

=> $\frac{39\frac{3}{8}}{2}$

=> $\frac{\frac{315}{8}}{2}$

=> ${\frac{315}{16}$

=>39.4

We know that the perimeter of the rectangle is

=> 2( L + B) = ${\frac{39.4}{2}$

=> 2( $2\frac{1}{2} \times x + x$ ) = 19.7

=> 2( $\frac{7}{2}x) = 19.7$

=> $3.5x = 19.7$

=> $x = \frac{19.7}{3.5}$

=> $x = 5.6$

Now length of the envelope =

=> $2\frac{1}{2} \times x$

=> $2.5 \times 5.6$

=> 14
