Mr. Foulkes teaches Biology. There is a lab room adjacent to his classroom.
|—— 40.8 ft ——-|
-
29.3 ft Classroom Lab

|—— 30.2 ft ——|
What is the area of the lab?
So 30.2 = 40.8 * 29.3 right?
To find the area of the lab, we can use the formula for the area of a rectangle, which is length multiplied by width. From the given information, we know that the length of the lab is 30.2 ft and the width of the lab is 40.8 ft. Therefore, to find the area of the lab, we need to multiply the length and the width together.
Area = Length x Width
Area = 30.2 ft x 40.8 ft
To multiply these numbers:
1. Line up the decimal points of the two numbers.
30.2
x 40.8
-------
2. Multiply the numbers as if they were whole numbers, ignoring the decimal points.
302 x 408 = 123216
3. Count the total number of decimal places in both numbers (in this case, one decimal place).
4. Place the decimal point in the product (123216) so that it lines up with the total number of decimal places.
12321.6
Therefore, the area of the lab is 12321.6 square feet.

as always, area = length * width
so plug in your numbers ...
