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.
