What is the width of a rectangle with a length of 12cm and area of 192cm2
2 answers:
Hello!
The width of the rectangle is
cm^2.
_____________________________
Formula for area is:
A = l × w
We know that we must multiply the length by the width to find the area.
Since we want to find one of the rectangle's dimensions, and not the area, we'll use the opposite operation.
What's the opposite of multiplication? Division!

Divide the area of the rectangle by its length to find the width:
W = A ÷ l
W = 192 ÷ 12
W = 16

<h3>What is compound interest?</h3>Interest that is added to a loan and deposit sum is known as compound interest. In our everyday lives, it is the notion that is employed the most frequently. Compound interest is calculated as a sum using the interest and principal accrued over time. Compound interest versus simple interest differ primarily in this way.
As per the data provided in the question,
Rate, r = 12%
After five years, the total amount, if Jane had saved at Mystic Bank,if Jane had saved at Mystic Bank would be:
For compounded quarterly,
n = 5 × 4
n = 20
A = 40000(1 + 12/(4 × 100))²⁰
A = 72244.44 (i)
If Jane placed her savings with the Four Rivers, then,
A = 40000(1 + 14/(2 × 100))¹⁰
A = 40000 × 1.9671
A = 78686.054 (ii)
Therefore, it is evident that case (ii) is higher than case (i). Jane must therefore deposit her savings in the four rivers bank.
