If the length of a rectangle is increased by 120 %, and its width is decreased by 20%,what happens to the area of the rectangle?

Answers

Answer 1

Answer: Let length of rectangle=x and width be y
.`. area=x*y
now new length=x+12x/10=22x/10
width=y-y/5=4y/5
now .....
new area=new length-new width=22x/10*4y/5
new area=88xy/50

Answer 2

Answer: The area of the rectangle will decrease because lets say the length is 2 and the width is 1
originally the area of the rectangle is lxw which is 2x1 is 2. But if we increase the length by 120% which will be 2.4 and increase the width decreased by 20% which is 0.8 then if we multiply them using the formula its 1.92 which decreased

We have been given that the physical therapist earns $49,830 a year and is single with no dependents.

To determine the amount withheld from his biweekly pay for state income tax.

Since the state income tax rate is 5% of taxable income.

So the amount withheld from his biweekly pay for state income tax as:

⇒ 5 % of 49,830

⇒ (5/100)49,830

⇒ (0.05)49,830

⇒ 2491.50

Therefore, the amount withheld from his biweekly pay for state income tax is $2491.5.
