Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  Please have a look at the photo

My answer:

a.How are L and W, and d related?

Because  L and W, and  d are the 3 size of an right-triangle. So we use pytagon theorem to fill in the blank:

$d^{2} = L^{2} + W^{2}$

b. If L is 7 units long and W is 5 units long, how long is d

Once again, we use pytagon theorem to find out d

$d^{2} = L^{2} + W^{2}$

<=> $d^{2} = 7^{2} + 5^{2}$

<=> $d^{2} = 74$

<=> d = $\sqrt{74}$

Hope it will find you well.
