Length Width To find the area (or the amount of space on the surface of the shape), we use the simple equation: Length x Width = Area (squared in., squared ft. etc.)
Length Width To find the area of a rectangle (or the amount of space on the surface of the shape), we use the same simple equation: Length x Width = Area (squared in., squared ft. etc.)
Now that you are an expert on area of squares and rectangles, can you use that knowledge to estimate how many small squares you can fit into a larger square?
Now, how would you figure out how many red squares would
fit into the blue
square?
1 ft. 1 ft. 5 ft. 5 ft. How many red squares do you think will fit into the blue square? How do you know this? Let's find out! Rectangle not drawn to scale
32.
How Many Squares Fit? 1 ft. 1 ft. 5 ft. 5 ft. Let’s count the number of red squares that can fit into the blue square. Rectangle not drawn to scale 1 2 3 4 5 6 7 3 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25
Now, look around the room for square or rectangular objects.
Use a ruler to measure the objects and use a calculator for any big numbers.
Make a chart and write down the name of the object, shape, length, width, equation and area of the object.
( REMEMBER TO USE LABLES. )
