Plywood is sold in rectangle sheets 4 feet wide and 8 feet long. How many 4x8 sheets of plywood are needed to completely cover a rectangle shaped floor measuring 16 feet by 12 feet.
First, we solve for the area of the rectangles. Recall that the area of a rectangle is just
A = L*W
where L = length and W = width.
Area of large rectangle:
A = 16*12
A = 192 ft^2
Area of small rectangle:
A = 4*8
A = 32 ft^2
Finally, we divide:
192/32 = 6 sheets of plywood
Hope this helps~ :)
