Question 240233
Hello, 
Let's note down the information we do have first. Lets show the shorter side
with x and the longer side by 2x-3. Ok, with this we can write an equation as:
x+x+(2x-3)+(2x-3)=24  Combine like terms. 
6x-6=24  Add 6 to both sides.
6x=30  Divide both sides by 6
x=5  So 5 cm is the length of the shorter sides. Plug in 5 to (2x-3) gives us: 
7 cm for the longer sides.
