## Steph_Rawr352 Group Title PLEASE HELLPP Solve P=2(l+w) for I. Fill out this chart. P= 14 w=2 I=? P= 22 w=8 I=? one year ago one year ago

Step 1: Expand the brackets on the right hand side. Step 2: Get all I terms on one side of the equals sign, everything else on the other side. Step 3: Get I on its own by division (will be by 2). Can you do these steps?

2. Steph_Rawr352 Group Title

ok so first I would use the distributive property for 2(l+w) ? so it would be 2l+2w?

3. Traxter Group Title

Yep that's Step 1 completed, now see if you can do steps 2 and 3 :)

4. Steph_Rawr352 Group Title

thanks!

5. Traxter Group Title

Let me know what you get and I'll tell you if you're correct.

6. Steph_Rawr352 Group Title

I got: p-2w/2

7. Traxter Group Title

Well done, make sure you include the brackets though: $l=\frac{(p-2w)}{2}$ Now all you need to do is substitute the values you're given into that :)

8. Steph_Rawr352 Group Title

oh ok thank you so much! (:

9. Traxter Group Title

No problem at all :)
