Answer:
Explanation:
The sides of the triangle are :
<span>24cm,28cm</span> and <span>36cm</span>
Explanation:
The ration of lengths are: <span>6:7:9</span>
Let the sides be denoted as:
<span>6x,7x</span> and <span>9x</span>
The perimeter <span>=88cm</span>
<span>6x+7x+9x=88</span>
<span>22x=88</span>
<span>x = </span>
<span>x=4</span>
The sides can be found as follows:
<span>6x=6×4=24cm</span>
<span>7x=7×4=28cm</span>
<span>9x=9×4=36c<span>m</span></span>
