design and measurement

Today we began to work on design and measurement. We handed in our finace sheets from yesterday which i did terrible on by the way. The design and measurement is like what we did in grade ten. taking measurements of shapes and calculating for diffrent questions asked like how many 30*30 tiles would fit in a room 445 cm long by 350 wide? well we had to figure that out today. WOHH seems easy but could be harder than i thought it could be.
