# MATH - area question

posted by on .

I need help on where to begin with this problem.

You are installing a new deck around your pool. The pool is rectangular with the dimensions 8m by 4m. The deck will surround the pool and will have a width by 2m.

What is the area of the deck?

I know that A=LxW and that the Area of the pool would be 32m(squared). But, how do I go about only finding the area of the deck?

Is this the right thing to do:

Would I add 2m onto the length and width making it 10m by 6m (find the total area of pool and deck together, and then subtract the pool area to just get the deck?)

If the deck is 2m wide, you'd have to add 4m to the length and the width, since there are two opposite sides (each 2m) in a rectangle. Calculate the area of the deck AND the pool.

Subtract the area of the pool from the above area.
