Answer:
Step-by-step explanation:
The figure is shown in the image attached.
Notice that the shaded light gray area can be calculated by the difference of the bigger square and the smaller square.
The area of the bigger square is:
The area of the smaller square is:
The difference between these areas is:
Therefore, the expression that can be used to find the light gray area is:
Additionally, the expression is also a right answer, because it's equivalent to the first answer.
Answer:
mode
Step-by-step explanation:
The equation for area is lw=a lengthxwidth=area so you put in what you know. (area and width) and get 18L=450. divide both sides by 18 to make the L alone. 18L becomes L and 450 becomes 25. Length = 25 feet
Therefore the answer is A.
Here is the formula that is used for answering.
