Step-by-step explanation:
The area of a rectangle (
) is represented by the following formula:

Where:
- Width.
- Length.
If length is increased by 120 %and width is decreased by 20 %, the percentage change in the area of the rectangle is: (
,
)



The area of the rectangle is increased in 76 percent.
Answer:
C; 4
Step-by-step explanation:
Mathematically, when two lines are perpendicular, the product of their slopes equal -1
in that case, we have it that;
m1 * m2 = -1
where m1 is the slope of the first line and m2 is the slope of the second line
Hence,
m2* -1/4 = -1
-m2/4 = -1
-m2 = -4
m2 = 4
