B. 72= 8h
In this case, h would represent 9. 72= 8(9)
<u>There is no requirement in the question. I'll calculate the area of the rectangle to help you with this question.</u>
Answer:
Step-by-step explanation:
<u>System of Equations</u>
Let's call y to the length of a rectangle, x to its width. There are two conditions that will help us to solve for x and y.
- The length is four less than three times the width. That is written as:
- The perimeter of the rectangle is 16 cm. The equation for this condition is:
Divide by 2:
To solve the system, we'll substitute the y in the first equation into the second:
Joining like terms:
Solving:
Find the value of y:
Thus, the length of the rectangle is 5 cm and its width is 3 cm. The area is calculated as:
The answer is true i think
