Example Question #14 : How To Find The Area Of A Rectangle
What is the area of a rectangle that has a length of and a width of ?
Recall how to find the area of a rectangle:
Now, plug in the given length and width to find the area.
When multiplying decimals together first move the decimal over so that the number is a whole integer.
Now we multiple the integers together.
From here, we need to move the decimal place back. In this particular problem we moved the decimal over a total of two decimal places.
Therefore our answer becomes,
Example Question #15 : How To Find The Area Of A Rectangle
What is the area of a rectangle that has a length of and a width of ?
Recall how to find the area of a rectangle:
Now, plug in the given length and width to find the area.
When multiplying fractions, multiply the numerators together and multiply the denominators together. After multiplication is done, find common factors in the numerator and denominator to cancel out and completely simplify the fraction. In this particular case the integer can be written as a fraction by putting it over one.
