Answer:
33, 11, 24 feet
Step-by-step explanation:
Let s represent the length of the second side. Then the length of the first side is 3s and the length of the third side is s+13. The perimeter is the sum of side lengths:
(3s) +(s) +(s +13) = 68
5s = 55 . . . . . subtract 13
s = 11 . . . . . . . divide by 5
The side lengths are ...
6/130
In finding the equivalent fraction of a number,yo have to multiply any number by the numerator and denominator. Example
3/65=3×2/65×2
=6/130
3.8
1/2*1/2=3/X
1/4=3/X
X=12
