Best ResponseYou've already chosen the best response.1Step 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?

Best ResponseYou've already chosen the best response.0ok so first I would use the distributive property for 2(l+w) ? so it would be 2l+2w?

Best ResponseYou've already chosen the best response.1Well done, make sure you include the brackets though: \[l=\frac{(p2w)}{2}\] Now all you need to do is substitute the values you're given into that :)
