The measurement unit is a definite magnitude of a quantity, defined and adopted by convention or by law. It is used as a standard for measurement of the same kind of quantity. Any other quantity of that kind can be expressed as a multiple of the unit of measurement. For example, a length is a physical quantity.
Deck definition is a flat area for walking on, that built across the space between the boat sides.
Joy is helping her father to build rectangular deck that measures 14ft by 19ft. Find the area of the deck using a mental strategy. Explain your thinking.
If we draw the deck, we have length 19ft and width 14ft. Then to find the area of the deck we get:
[tex]19*14 ft = 266 ft^2[/tex]
[tex](14*20)-(14*1) = 280-14 ft^2 = 266 ft^2[/tex]
The foot is a unit for measuring length. The foot is one of the Imperial units and U.S. customary units. One foot contains 12 inches, while a foot is equal to 12 inches, and a yard is made up of 3ft.
