Answer:
Area of the rectangular doormat = 2/5 m²
Step-by-step explanation:
Length of the rectangular doormat = 4/5m
Width of the rectangular doormat = 1/2m
What is the area of the doormat?
Area of a rectangle = length × width
= 4/5m × 1/2m
= (4×1) / (5×2)
= 4 / 10
= 2/5 m²
Area of the rectangular doormat = 2/5 m²
There are two -main- approaches to answer this problem. By using the sine identity, or applying law of sines.
We'll do the sine trig. identity, as it is the most effective.
Given an angle '

' in a right triangle, '

' is defined as the opposite side of the triangle to the given angle, over the triangle's hypotenuse.
So, for this setup:

Now, we solve for x:
So, answer is 3.4
The amount of interest she will earn in one year will be 5 dollars and 12 cents.
<h3>What is Simple interest?</h3>
The normal interest levied on the amount borrowed from any bank on a yearly basis is called the simple interest.
Given that:-
- The interest of 3.2% per year
- Invests $160 and no money will be added or removed from the investment.
The simple interest amount will be:-
SI = ( P x R x T ) / 100
SI = ( 160 x x 3.2 x 1 ) / 100
SI = $5.12
Therefore the amount of interest she will earn in one year will be 5 dollars and 12 cents.
