Question 1105957
<br>
If each dimension was increased by 2cm, then the perimeter was increased by 8cm.  So the original perimeter was 62-8=54cm.<br>
The width is 4/5 the length, so call the width 4x and the length 5x.<br>
Width plus length is half the perimeter:
{{{4x+5x=54/2 = 27}}}
{{{9x=27}}}
{{{x=3}}}<br>
The length is 4x=12cm; the length is 5x=15cm.
